As mentioned in my other comment already, it's great to see someone is trying to provide a better alternative to asdf!

From what I can tell by looking at the documentation of `rtx install`,

  rtx install                # installs all runtimes specified in .tool-versions for installed plugins

and of `rtx plugins install`,

  install a plugin

  note that rtx automatically can install plugins when you install a runtime

e.g.: `rtx install nodejs@18` will autoinstall the nodejs plugin

I take it there is still no way in rtx to simply install all plugins and runtimes listed in .tool-versions, without listing them one by one on the command line? Put differently, I would expect `rtx install` to install all runtimes specified in .tool-versions, including any plugins that are not installed yet.

Would this be something that you would consider adding? I'm asking because not being able to install all plugins mentioned in .tool-versions automatically has been my biggest gripe with asdf.
