It seems even more KISS to avoid managed alternatives altogether and let the user handle them.

python2 and python3 are two different languages and any python script should be clear about what language they are written in.  A shebang of /usr/bin/python is a bug, in my view, that the OS should not try to "fix".

Currently, we offer a "python" package and a "python2" package.  Similarly for lua, we offer packages "lua", "lua52", and "lua51".  The way this behaves is clear and simple.

I probably am overlooking a use case where managed alternatives are important.  Can someone give a good example to help the brainstorm?

Best, Daan van Rossum
