It will probably come to something like that (for the Unicode issue alone) but it would be a disaster. Python has always had an issue with ongoing changes that break existing code. That was the idea behind Py3, that we would do all the breakage at once and be done with it forever. Ironically that made Py2 a much better target for a time as it was not changing very much.
