Not sure what do you mean by venv but for local use you aren't
required to use Python interpreters from the distribution and can e.g.
use pyenv to install any other one.
I was in fact about to suggest the same thing Andrey did here. For any
local-use stuff which requires one or more Python versions beyond the
system-installed Python version, this is my recommended solution to use
pyenv and then have the local installs alongside Debian's installed Python.
I also want to make a few things known about 'downstream' 'in Ubuntu
that you refer to. The problem we see routinely 'downstream' is people
try and change their Python version away from the system preferred
Python version, thus breaking things. It happens way more than I'd like
to admit (just look at Ask Ubuntu and the number of python errors we can
attribute to User Error in this exact way), and usually I suggest pyenv
[1] to allow userspace installations of Python isolated from system
Python that works for those cases you need older versions.
I do this routinely even downstream on other distros. In fact, wherever
you are required to use *older* Python or *newer* Python than is
available in your distro - Debian, Ubuntu, Mint, etc. - I always point
at PyEnv as a solution.
