I would say a big part of the problem is that all of these use cases
are outside of mainline. Why should mainline support something which
is not actually used in mainline.

So i would suggest your first step is to bring some of these devices
into mainline. Once in mainline, it becomes a mainline issue, and
people will help get it solved.
