Yes, I was considering this point. Just wondering, what would break (in
theory: nothing should) and how to perform the validation. Didn't want
to do such change without more feedback, so now - if you already
summoned this subject, I'll wait a few days for any comments.

I've already reviewed these and only one (re)definition needs to be
adjusted (in /usr/lib/rpm/macros.d/pld), remaining macros seem to be
cascading properly.

I don't care about all this GNU/crap either, but using some Fedora
systems this directory was really convenient. My personal rationale is
'follow the world', just to avoid being different than all the rest.
