My question is "why is this a problem"?  (Why is debugging on for normal usage?)

If you want to enable debugging with RPM, leaving the files is the right answer.
 Otherwise, as mentioned in the post it's REALLY hard to debug scriptlet failures.

As for the rootfs.py cleaning them up, it's simply not possible -- assuming they
end up in a shared tmp dir, as you wouldn't have any idea who created them..
this build, or another, or a system process....  (Now if they only install into
the image's /var/tmp, thats a completely different case -- but I still question
why debug is enabled at all.)
