I love pipx and I'm glad it exists at this point because it make
The main issue is that each virtualenv takes space, lots of space.
I have currently 57 apps installed via pipx on my laptop, and the 57
environments take almost 1 GB already.

There is probably a clever way to reuse common packages (probably via
clever symlinking) and reduce the footprint of these installations.
Still, I'm glad that pipx exists as it is now, and that it has been
packaged on Ubuntu 20.04 and later (and probably other distros as well).
Having pipx (or something similar) installed by the distro, and the distro
focussed on packaging only the packages that are needed for its own sake,
means that we could go past the controversies between the Python community
and the Debian (or other distros) packagers community, which are based on
different goals and assumption, such as this one:
