This can be reproduced in the emulators too: using the default pool: IP Address Pool: 192.168.137.100 - 192.168.137.199 and try add any address outside of this, like 192.168.137.75

Hi,

 

Regarding your point 1.

 

You are right in that this used to be possible on older TP-Link routers and many users, including myself, would have liked this to be kept that way.

 

However, big players in the IT industry apparently have decided that a reservation of an IP address from outside the DHCP address pool is not appropriate, and now smaller players are following suit.

Hello,

 

well, yes and no. Not all fallow this "nonsense"... 
I understand this too, but not agree with it.
I can accept this, IF its fully implemented; we get an option to define an exclusion range, and working as it has written in the last paragraph: 
" If you do not want to distribute addresses from the whole subnet, you can also define an exclusion range. A reservation that falls into an exclusion range will still work."
