That is not an elegant solution. That way you would forever had 3 in the name, even for future version of Python (e.g. python4, that will not break compatibility with old source code and thus making a .py4 wouldn't make sense). In your shell you don't run "java8" or "java11", you just run "java", and then it's the matter of what version of java JDK you have in your PATH. The same with all other language interpreters and compilers, you don't run gcc9 or node14. Why doing something different for python? Really, the mistake of python3 was to break compatibility with past programs. A lot of changes could have been done more gradually, in the first version require a __future__ import, then gradually remove compatibility with old features, and then remove them completely, making the new way the default and thus no longer require the __future__ import. And I think it will be the way for next python version, so in theory we will never have the same problem again. Also to me it was an error for distros to continue packaging python2 as python. Other distributions, like ArchLinux, switched everything to python3 as default a lot of time ago, it's only Ubuntu that continued to ship python2 as python, thus making a lot of programmers relying on it. It would make sense that the command without the name refers to the latest version, and not the legacy one.
