You've made general comments about supporting our users, and I reacted
to that and wrote that we can't always please our users because of real
world difficulties to do that.

Now, if you're back to supporting Python 2.7, if the Debian project is
committed to that, of course, I support the decision if it's a team

Wow, hopefully not ! LTS is an effort by the Debian project. What the
external company does  is an effort to *FUND* individual to work on it.
Currently, only Freexian does this sponsor gathering and redistribution
work, but it's my understanding that it would be perfectly valid (but
IMO probably not desirable at this point) that another company competes
with this funding effort.

That's a huge difference. If it was only the way you wrote, IE only a
private company stuff, then the LTS uploads wouldn't be allowed on the
Debian infrastructure. If here, I'm mistaking, then please, correct me,
and let's discuss again about LTS and how Debian supports it.

So yes, LTS is fully part of the Debian project, and how Python 2.7 is
supported should IMO very much be our concern. Now, we think that we
should only support Python 2.7 for more than until Buster is EOL and
becomes an LTS, I support this restriction. Though it'd be nice if we
had this consensus before Buster is frozen and have the discussion
closed early.

That is very wrong, I very much agree with what you wrote just above.

But what about softly removing Python 2 support when there's no reverse
(build-)dependency in the archive, like I already started to do here and
there? Do you think that's acceptable?

If you do think it's acceptable, then why not starting that effort as
soon as possible, since it takes a much much longer time to do things
this way, which is also the way that is the least disrupting for our
users? (/me just earned a godwin point for invoking social contract #4:)
