Well, I usually do not like to see __maybe_unused because that is prone
to bit-rot and loses its usefulness. Looking into the recent git logs
most -Wunused-function led to the code removal (which is really good
but the compiler is likely to do that already so the overall impact is
not that large) or more ifdefery. I do not really see many instance of
__maybe_unused.
