As a developer, I will probably want to state the Python dialect that
was used to write the module. Each dialect comes with hundreds of
features. I don't want to list them individually (even if I could).

That's an explicit program of destroying backwards-compatibility: a war
on legacy code. That may be the Python way, but it's not a necessary
strategy.

Two branches? I would imagine there would be dozens of "branches" in the
interpreter if the latest interpreter were to support all past Python
dialects (as it should, IMO).
