Yep.

This is a repetitive problem, and I fully agree with your concern about
stuff which is supposed to be arch-independent being designed with only
DT in mind.

New core kernel features should *not* be designed with only DT in mind -
DT is not the only firmware description language which the kernel
supports.  Folk need to understand that if they design a new arch
independent kernel feature where the sole use case is with DT, that new
feature is probably going to get rejected, especially when it's
something as generic as resource tracking.

The world is not DT only.
