I don't see how this would break anything, since we wouldn't advertise
HT capabilities (for now). My point was that that the standard doesn't
(currently) define this, so I think it should be a separate second step
for 5/10 MHz channels to see how to do it in a way that wouldn't break
when/if the standard is changed to allow it, etc.
