I have now read the "git migration, next steps" thread. After that the 
situation doesn't seem to be so easy. What I see is that Distributors have 
valid arguments against a split.

I'll try to summarize the thread as neutral/balanced as possible:


If I understand correctly, one of the issues would be if the change is
sudden and not announced ahead long enough. From 
http://mail.kde.org/pipermail/release-team/2011-June/004875.html:

This issue can easily be avoided, by announcing early enough.

Are you sure about Fedora?

Other statements:

Summary of concerns in http://mail.kde.org/pipermail/release-team/2011-
June/004874.html:

There are also some arguments for splitting:

There is a proposed compromise solution, but this makes more work for the kde-
release team. http://mail.kde.org/pipermail/release-team/2011-June/004868.html

I am not sure any longer whether splitting is worth the trouble. I am getting 
the impression that it could also effectively lead to an even more fragmented 
kde-multimedia.
