I'm not sure what you are asking? Treat DTBs like kernel drivers. If
you make hardware and you want distros to run on it, you have to
provide the DTB for that hardware to mainline+distros.
Remember, there are two ways to view DTB:
a) It comes from the firmware and you have to live with whatever
crap the firmware does
b) It comes from the kernel, must match the kernel, and we don't
have to tolerate crap in the DTB.
Both make sense, but, IMHO, minimizing the occurrence of 'a' is a
good goal...
