I of course welcome vital projects such as GCompris. GPL3 topic will
be hopefully resolved. Relicensing  to v2+ would be a solution, anyone
is then free to set GPL3+ for her copy.

Another question arises from the GNU copyright assignment [1]. This is
a precedence for me, correct me if I am wrong, but KDE has no code
that's assigned to the (USA) FSF. For example I can imagine the above
relicensing would require consent of FSF. It's unlike other KDE
projects I know.

This is like a hybrid, one leg in KDE, one leg in FSF so far and
really, a distraction or me. If this is mostly work from scratch, I
hope relicensing would be possible.
