Yeah, I would agree that it is good form to avoid modifying the inputs
of a rule.

This warning is pretty annoying since it is intentional but we do not
have great tools to hide just this one instance it seems... This is
probably worth a comment.

It would be nice if this section could be marked as NOLOAD from the
beginning but that will mess with extracting .modinfo via objcopy from
my brief testing.

Cheers,
