Honestly, I think technical means wouldn't stop everyone from working
of features instead of porting. Global agreement to the plan would
make the trick. So I would be in favour of branching as usual. Unless
I misunderstood something.

Example to show things are not simply linear: My feature branch is
kind of splitted already, part of the code is in the predicate repo. A
few other smaller repos will follow. Developing/adopting predicate is
a part of the porting process. Basically calligradb won't be
Qt5-ported, instead, predicate will be ported to Qt5 and then Kexi
will be ported to it. That saves unnecessary Qt5-port of kexidb.
