This is a missing feature, indeed! I have just upgraded (or thought I had upgraded) from my EdgeRouter X to the ER707-M2 to have an all-in-one solution with Omada, only to find out that I will now...

So just that you know: I'm using two EAP 245 in my house in a wall-mount configuration. It is a shame that tp-link does not provide an official wall mounting access point with similar throughput...
