I don't get the logic behind your battletested thought. Generally it might be true that finally python 3 is now the default for new projects but that doesn't mean that there will be a switch to python 3 as default enviroment. There are still a lot of base libs which are not ported to python 3. Most often nobody has interest in porting them. Some are, but then often as a complete rewrite, which are not backwards compatible. Until Python 3 is the default env it will take a few more years.
