Hi Richard, To stay focused, I just reply to the main points of your email.

And no hacks had to be introduced. We can take that as indicator that the same works for PyQt. * Huge projects exist that have a codebase compatible with Python2 and Python 3 (e.g. pandas [1]). We can take that as an indicator that a compatible codebase is possible.

At the moment I just do not believe in this approach. * Usage of compatibility wrappers will be optional for plugin developers. But they are very desirable for plugin developers who have to support concurrent versions. * If it turns out that it is harder than expected we will still be free to just completely dismiss compatibility support. But I wouldn't want to not even try it because of believes and feelings.
