Your point about the diversity of the router hardware ecosystem is an important one, and from what I can tell, makes up a significant portion of the OpenWRT project.

I think though that the "industry" work on QoS and rate control has been pretty dismal and counter-productive. The major improvements in QoS in OpenWRT didn't come from the router industry, and the router industry hasn't been speedy about incorporating it. Fixes for queuing and rate control in the WiFi stack are also coming from outside (when they come), and who knows how long they will take to get mainstreamed.
