I go between different languages a lot so having a command line interface that is consistent with the one I use in Python (uv) would definitely be appreciated. I mostly use Ruby for single-file scripts with no dependencies, which means I don't do projects often enough to remember how to use bundle/gem/rvm/whatever. It seems to me like `rv` is not quite ready to fully replace them just yet but I'm excited to see where the project goes.
I'm also excited about `rv tool` because I've been having to re-install rubocop and ruby-lsp gems every time the minor version of the system Ruby is updated. It's just a few commands every year (and I'm sure it's a skill issue) but having things "just work" with a single `rvx rubocop` command will be sweet.
