I, on the other hand, don't care what language the tools are written in.

I do get the sentiment that a user of these tools, being a Python developer could in theory contribute to them.

But, if a tool does its job, I don't care if it's not "in Python". Moreover, I imagine there is a class of problems with the Python environment setup that'd break the tool that could help you fix it if the tool itself is written in Python.

It is well known, and not Python-specific, that using a different language/interpreter for development tools eliminates large classes of bootstrapping complications and conflicts.

If there are two versions of X, it becomes possible to use the wrong one.

If a tool to manage X depends on X, some of the changes that we would like the tool to perform are more difficult, imperfect or practically impossible.
