Well, there are already hooks to fake the TX time spent, right? Having
both TX and RX busy times available to rate control so it can better
schedule TX loads based on current RX workloads would be nice.

Having access to schedule which peer and how much to send to each peer
would be nice. Stuff like "peer X only can have up to x ms in this WME
class this round", so you don't have a busy, close peer monopolising
the air. It also means you can start doing smart things with far away
peers who retransmit a lot - they're likely tying up a lot of airtime.

None of this is new. It's just, you know, new to open source. :-)
