probably the branch name in front? I have the feeling it'd confuse the 
"version number extractors" a bit less.

So basically kio-extras-qt5-xxx and kio-extras-qt6-xxx (or without the qt) (or 
with kf instead of qt).

This is basically a variant of a) in which no longer release a KF5-based-
tarball but the distributions do some kind of renaming to make sure both the 
"old" KF5-based package and the "new" KF6-based package can both be installed 
at the same time.
