I think I understand your rationale to stop shipping /usr/bin/python and
once the unversioned symlink disappears from use in Debian then at least
that particular avenue to breaking one's system disappears.
What I don't understand is why any changes to package names or dependencies
are required to achieve that goal.
It sounds like a reasonable amount of work in your proposal, but once we no
longer have any Python 2 applications left at some stage in the bullseye
cycle, isn't the following sufficient?

and then either later in the bullseye or bookworm cycles, those python-
defaults simply go away along with all the other 'unversioned' python module
and interpreter packages.
What have I (and others!) missed that would make a rather elaborate
packaging dance preferable to this?
from my point of view this doesn't address:
- being able to de-install the python command for buster, if
people don't use it. Most dependencies are auto-generated, so
these could be replaced by dependencies on python2. I would
assume that the majority of users won't have to install the
python package anymore, unless they are doing python2
- Not having a python package in bullseye (buster+1), but a
python2 package doesn't point to any "default" anymore. Many
users are installing just python, because it's the unversioned
package. So make it clear that this is another version, and
with having the choice of python2 and python3, most users will
Note that with the command-not-found package installed (and using python3), and
not having python installed, you get now a message
Command 'python' not found, but can be installed with:
sudo apt install python3

You also have python3 installed, you can run 'python3' instead.
Assuming that you only have python2 installed in buster, you get this hint
already in buster, pointing to python3. You can't do this without a separate
