You're probably just going to see this as further confirmation of
your opinion, or yet another person telling you that you're doing it
wrong, but as someone who also writes rather a lot of Python
programs for a living I learned long ago to not develop against the
"system" on any platform. I use sid/unstable for my development
systems, but I consider the python3 package in it to have two uses:
Testing new packages of software which are targeting a future Debian
stable release, and running other packaged things which are already
part of Debian.

For software development work, I compile my own Python interpreters
and libraries, because I need to develop against a variety of
different versions of these, sometimes in chroots, to be able to
target other distros and releases thereof. I keep all these in my
homedir or otherwise outside of normal system-wide installation
paths. Bear in mind that this isn't just a Debian problem, for
decades Red Hat has also advised programmers not to rely on their
/usr/bin/python for custom development because it is patched and
tuned specifically for running system applications packaged for
their distro and not intended as a general-purpose Python
distribution.
