Some drivers do not support WPA ad-hoc. Anyway, if you are talking about
a layer 2 bridge, adhoc mode would not really work either since it does
not allow frames to be sent with foreign source address.

That sounds more like information that would be more in scope in places
where driver/hardware capabilities are described. Number of drivers
support AP mode and hostapd/wpa_supplicant can use that functionality if
it is available.
