what exactly is your issue? I've been using rvm for a decade(?) without any major pain. Cross-language tools such as mise or asdf also seem to work ok.

I can relate to the "I wish we didn't need a second tool", but it doesn't seem like much of a mess.

Of all the languages I've touched, managing multiple ruby versions has been one of the easiest.

I've been using pyenv for a decade before uv and it wasn't a "major pain" either. But compared to uv it was infinitely more complex, because uv manages python versions seamlessly.

If python version changes in an uv-managed project, you don't have to do any extra step, just run "uv sync" as you normally do when you want to install updated dependencies. uv automatically detects it needs a new python, downloads it, re-creates the virtual environment with it and installs the deps all in one command.

And since it's the command which everyone does anytime a dependency update is required, no dev is gonna panic why the app is not working after we merge in some new code which requires newer python cause he missed the python update memo.
