wpa_supplicant does actually use MAC address -based limitation for one
use cases (P2P group formation). However, I'd like to make it clear that
this is not really authentication and "advanced AP feature".. It is
trivial to change the MAC address of a device and this does not add any
real security.

If there is a reasonable use case for it, sure, it could be added. No
such use case has come up so far, though..

Well, they are both already sharing the same source code repository.
Whether they will ever be fully merged in a way that there is no option
to build something similar to what is built today is unclear, but
anyway, the main missing part from wpa_supplicant is in providing new
configuration options to take any of the existing hostapd functionality
into use. If there are good use cases for such functions, they can be
added on top of the current wpa_supplicant configuration mechanism.
