And since before that, when we started turning to additional packages managers installed with package managers. Pip etc. mean that an “apt upgrade” isn’t enough, when it really “should” be (used to be) in a well managed system.
Then we layered _another_ level of package management on top with Flatpak etc.
I don’t think anyone has _really_ been - in practice - able to understand how many versions of Python (or shells or ruby or Perl etc…) are installed on any system for a decade or two now.
[Edit to add: and I forgot entirely about venvs (and other language’s equivalents). We put package managers into packages! Now there can be a different version of every package for every script on your system. In every container. And Python even has more than one venv system to choose from!]
[Yes, I use all these things - it’s so hard _not_ to and still use modern software or participate in modern software development…]
