Given that with Yocto you're building a full system image it's not
super obvious to me that it is particularly harder to ship udev rules in
the image as opposed to modifying the DT.  It's a little more annoying
but not drastically so and it's not creating a burden on the ABI for
something that's mainly used within a vertically integrated software
stack.

No, that needs to happen along with the code change.
