For values and #defines that are in public specs, does it matter? It's
good to have full definitions in the .h files for whenever possible for
stuff like this to make it easy for people to write code to use them :)

Good to know your position on this. It is one of the per-maintainer
thingies: Some maintainers don't accept defines if they are not used.
Usually I stay away from defining them to avoid the resulting arguments/
discussions. If you are ok with it, so am I.

#defines are trivial, and are good for documenting things. We have loads
of drivers that do this to make it a good way to document the full
hardware or specification despite not using all of the defines. They
also are not a maintenance burden.
I don't take new apis that no one uses in-kernel as that's just ripe for
deletion and is a maintenance burden. It makes no sense to add and then
remove something right away :)
