From this, I conclude that it should be "safe by

/var/cache/<dir> directories and/or files below such directories upon
final package removal.
ATM, none of the packages in Fedora using /var/cache/<dir> (e.g. yum,
mock, abrt) does so.
vdr-osdteletext does, but that's a drop in the ocean.
This leads to /var/cache/ gradually filling up with
orphaned/unused files, e.g. when temporarily installing mock or abrt.
FWIW, no objections to mandating removal of that stuff here.
