Funny. Yeah I'm pretty sure everybody ignores that. Of course maybe you
can't get a 1x1 AP certified as an AP, but surely that'll happen with a
P2P GO all the time.

I don't want to honour it. In fact, the more I think about it the less I
want to honour the 0-7 part here, since that just made the code more
complex and almost nobody will be using this override anyway.
