I've written up the proposal I made a few days ago for a /usr/bin/python
launcher that keeps the API of being Python 2, but lets scripts opt in to
running on Python 3:

I share the desire for /usr/bin/python to maintain its API of being Python
2, but I also want to be able to write polyglot Python 2/3 scripts that
run everyhwere -- including on Debian machines with just Python 3. So this
is a way of "doing something else with /usr/bin/python" that's
backwards-compatible for us and all the other distros. It even happens to
be be kind of backwards-compatible for Arch, and Barry's point about
aligning the desires of the distros is a very good one.
Let me know if you think this is a good or bad idea: I'll submit this as a
PEP as soon as we have rough consensus that this is a good idea. (We can
bikeshed the details once the idea itself is a draft PEP.)
