I've been told that the plan is that ALL the KDE SC modules will eventually 
migrate to git, but I don't know any details about when and how this will 
happen for kdesdk. You have to talk to the people driving the git migration 
and/or to the kdesdk module coordinator.

If kdesdk is going for split repos, a libdiff2 as a separate submodule of 
kdesdk (i.e. a separate git module which would be listed as part of kdesdk in 
the tree on projects.kde.org) is certainly doable (and in line with what e.g. 
kdegraphics is doing).

The problem with moving it out of kdesdk is, where do we move it to?
1. It depends on kdelibs, so kdesupport is the wrong place.
2. We can't add it to kdelibs before 5.0 because kdelibs 4.x is permafrozen. 
(And I've tried to fight that pointless freeze on kde-core-devel, with no 
success.)
3. There's no suitable module between kdelibs and kdesdk.

If kdesdk is getting split anyway, having libdiff2 become one of its submodules 
looks like the sanest solution to me.
