/usr/bin/python3 deprecation and enforcing /usr/bin/python

[Antoine Beaupré <anarcat@debian.org>]

Hi!

Debian has shipped Python 3 as /usr/bin/python3 for a while now. For
some time, we've also shipped a python-is-python3 package that ships a
symlink from /usr/bin/python to /usr/bin/python as well, but it's not
installed by default.

I'm assuming that most distributions outside of Debian, at this point,
have shipped /usr/bin/python as Python 3 for couple of years, as far as
I know (although I haven't surveyed that formally).

I've been wondering whether it's time we finally make this
change. Concretely, I think it means:

 1. deprecating /usr/bin/python3
 2. shipping Python 3 as /usr/bin/python directly

I think we should do this for Debian 14 (forky), and stop shipping
python3 altogether in Debian 15 (?).

Thoughts?

A.
