Right, sounds like what I intended to say ;)

Sure, that's the risk.  I'm also not sure why we have make prediction what the
we'll find when porting to py3/pyqt5 and use those to make plans.

And when we have that, we actually know how large the impact of py3/pyqt5 is -
and can decide if it's better to merge the branch back to master before 2.14 or
after.  If it's feasible to have a version that supports py2/3, pyqt4/5 and
Qt4/5 it's before 2.14 and otherwise it's after.
