I'm adding packaging Mailing List, seems to me that we can get more help
here. 
I have a lot of questions on this topic, not just /usr/share
vs /usr/libexec also vs /usr/lib .

>From what I understand, this is a problem that was created from Debian
translations. Debian don't have /usr/lib64/ and put all in /usr/lib, so
when we are packaging things that came "debianized". We got problems
when have things in /usr/lib/package and aren't libs and or are noarch
things. What we should do ? put it in /usr/libexec ? in /usr/share ? or
have a /usr/lib even for x86_64 ? 

We got weird examples: /usr/lib/rpm, /usr/lib/systemd/
and /usr/lib/udev/ shouldn't be in /usr/share/rpm etc ? 

Thanks,
