Changing the major version should be done for incompatible changes, and just doing it after 3.9 will probably just create confusion for both users that will wonder if it's incompatible with Python 3 and for things like the executable name. Hopefully we won't need to jump to Python 4 for a long time.
Changing the major version number is a much bigger political and psychological step than just bumping 3 to 4. I say let's put it off as long as possible, and there's nothing wrong with two digit minor versions.
