I have to say I'm not seeing any evidence of this in the patches I'm
seeing, and I'm not sure what the connection with IS_ENABLED() is?  It's
a reasonable idea, just likely to surprise people given the amount of
boilerplate we've got for things like PM - I guess we'd need to make
sure those macros do references as well, they're the main users of
ifdefs.
