Is it really a requirement that existing Py2 code must work unchanged in Py3? Why can't someone write a third-party library that does what these projects need, and that works in both Py2 and Py3, so that these projects can be modified to use that library and thus get on with their porting to Py3? Or rather one library that does what some projects need and another one that does what other projects need, because it's quite likely that the requirements are not really as largely identical as it seems when seen through the old and milky Py2 glasses. One idea of designing a Py3 was to simplify the language. Getting all Py2 "features" back in doesn't help on that path. If something can easily be done in an external module, I think it should be done there.
