Personally it's more about familiarity, I dev Rust so I know that I have all the prerequisites and setting this up should be trivial, meanwhile I don't do a lot of Python work so getting that to work might be a bigger commitment.

I don't do a lot of Go either but at least Go generates freestanding binaries so if I install it in precompiled form I know that it will be fairly frictionless and won't rely on half a billion dependencies (which may or may not conflict with something else). I use a bunch of Go programs regularly (like docker or Arch's yay package manager) and it never gets on in the way.

On the other hand if it's an npm package I don't even think about it.
