Well imagine you have a driver for some hardware that can do
beamforming, and the same driver can also work with hardware that
doesn't. If we restrict remote caps, like we do for HT, the driver
doesn't have to worry about this but can just do whatever the remote
caps say is possible. If we don't restrict it, the driver has to also
check its own caps.

you mean to say some drivers which dont provide its own VHT caps, will use remote STA VHT caps as its own?
If so I feel not correct posing remote STA caps as local caps.


We can do this, and I suspect it will be simpler, but it needs to be
*very clearly* documented since VHT will then be different from HT.
