But it too can't ever create QoS-data frames or negotiate TXOPs afaict,
unless it does more than we want in hardware.

Which isn't really a concern to the driver since only mac80211 will need
to be changed for that.

I suppose the question is: what are we missing in mac80211 now? It seems
that we have no way of sending out QoS-data frames and that seems weird.
Nor do we parse TXOP information etc. Possibly this is because we
support WME and that's based on an early 802.11e draft?
