Between virtualenvs, containers, or just plain ol&#x27; `make altinstall`, there are enough ways to run a python application that _doesn&#x27;t_ use the system python interpreter that this shouldn&#x27;t be an issue. Not to mention that most linux distros have packages set up in a way to allow python 2 and python 3 to be installed simultaneously, without interfering with system applications that rely on the version of python that is shipped with the OS.
