I don't think keeping `python` is a good idea, this would make Emacs
considered to be buggy in Debian.

Please see https://wiki.debian.org/Python :
...
NOTE: Debian testing (bullseye) has removed the "python" package and
the '/usr/bin/python' symlink due to the deprecation of Python 2. No
packaged scripts should depend on the existence of '/usr/bin/python':
if they do, that is a bug that should be reported to Debian. You can
use the 'python-is-python3' or 'python-is-python2' packages to restore
an appropriate '/usr/bin/python' symlink for third-party or legacy
scripts.
...

Cheers,
Balint
