As you say, switching means /usr/bin/python -> /usr/bin/python3. And yes, that is a very valid point about the naming, I think.

I agree about the renaming. Having said that, I don't like that the users will need to install python2-foo or python3-foo, not just python-foo. On the other hand, the normal users will just get stuff and update it. The developers using various versions of python might actually appreciate the knowledge of what they are installing.

Sounds good to me.
