Upgrade ethernet mesh home network with EasyMesh/Deco

Hello!
I’d like to ask for help for modifying/extending my home network. Please observe the first scheme. This is what I have right now. I have two cables coming out of the main router to the places that I need WIFI the most. The walls are very thick and I must be able to provide a wired connection to these places. I cannot introduce any more cables, nor need to. One of the cables is connected to the main Deco and the other is connected to the secondary router in House 2. Deco works in AP mode.
What needs to be done is to replace the secondary router in House 2 with something new (because the router is old and causes trouble and because I’d like to extend the mesh). Now, the obvious solution would be to replace it with another Deco and extend the mesh network. This is where I hit the first problem. TP-Link support said I will be able to pull this off but I will lose the mesh capability because Ethernet connection must be between the nodes. I.e. I won’t have a mesh between the two houses. Again, new cables is not an option.
So, I came up with two scenarios where I think I can have everything that I want.
First. Maybe the only way I can make use of the Deco mesh. Please observe the new proposal which extends my current setup with two more Deco M4 and a switch like TL-SG108.
Is this a valid scenario where I can keep a stable network, a mesh connection between all four Deco nodes and be able to extend with more wireless Decos in the future?
Second. I also researched an EasyMesh solution where I’d drop the Deco technology completely. Apparently, I have only one choice of a range extender that is capable of creating a mesh through Ethernet connection. Luckily, it seems to suit my needs anyway and be at a reasonable price. I adore the simplicity of this solution but I could barely find any information about such scenario. Would this work properly with two RE315 extenders connected to the main router? Would it really create a mesh network? Can I add more RE315 extenders connected to the router or the other extenders wirelessly?
Are both of those scenarios valid/good and which one am I supposed to choose? Or are there any better options than those I shared?

"I do hope you keep connecting the satellite Deco M4 in house 2 to the main Deco M4 in house 1, instead of the Archer AX20."
Mate, am I part of some social experiment?
No, I'm not connecting the two Decos with each other. Do you know why? BECAUSE YOU TOLD ME, I CAN CONNECT BOTH TO MY ROUTER VIA ETHERNET. Exactly the way I want to. That's what happened. If you feel any doubts, feel free to read your own comments here.
I'm glad you put the effort to modify my scheme, but that's not how it works in real life. You moved the main Deco from 2nd floor to first. Who says I want to do this?
"including factors related to the actual Ethernet deployment structures between the two houses."
Bulls**t. The "factors" include a single cable that is proven to work for years. Grab two Decos and a router and reproduce the problem yourself. There is nothing specific about my case.
Tell me how to troubleshoot this piece of c**p you call "Deco".

Hi, I'm definitely sure that when Deco is in AP mode, both can be connected to the main router via Ethernet cables, which is one of the common scenarios for Deco Ethernet Backhaul:
General questions about Ethernet Backhaul feature on your Deco
The hardware themselves have no issue as we used to set them first in house 1 and they work well. They also works when the satellite is connected to the main M4 directly.
Ethernet Backhaul between Decos involves more than just a basic Ethernet cable connection. I understand your frustration, and I also have my assessment based on the previous technical experience.
Further troubleshooting will go through the email, and the case will be escalated to our senior engineers directly.
Thank you very much.
Best regards.

So, what do we do now? I'm not explaining the whole thing for a 3rd time to whoever wants to get involved. How do I make this piece of c**p work?

Hi, I've left a note on the detailed problem, your request, as well as the current network topology of the two houses. There is no need to repeat the issue.
You might need to start replying to the support ticket #TKID250443885 first to further cooperate with our senior engineers.
Best regards.

I have no idea what does this mean. Where do I reply to what? Tell me the exact steps. And why do these guys don't post here, so it can be valuable for other users too?

Hi, Different teams would have their working focus and service methods. I will deal with daily inquiries about Deco products within the community. For issues I can't figure out, I will seek additional assistance from the engineers. The engineers didn't have to engage in community responses, and I can't request their involvement in this aspect.
Did you receive an email from the support.forum@tp-link.com? They usually add some further troubleshooting suggestions via email, and you can reply to this email with the possible results.
If the problem can be resolved using specific suggestions that are valuable for reference, we will organize and share such cases with the community.
Best regards.
