Ad-hoc was never very high on the WiFi chipset vendors' support list to
start with, and hasn't gained in popularity since. I'm not sure how
well it is supported nowadays. In Ad-Hoc networks it's difficult to do
WPA security, as both WPA roles need to be implemented. Discussions I
can find on the ml start from July 17th, 2011 and July 26th, 2012.
Please see the archives for the discussions and conclusions.

See those previous mail threads. Upstreaming is of course very nice,
but then one needs to be pretty sure that the feature also works across
(all the) other chipsets as well. For all the other normal use cases
except B.A.T.M.A.N., WiFi P2P is already supported. That said, WiFi P2P
definitely needs some more love and care, and even here the use cases
aren't that widely spread.
Cheers,
Patrik
