Add `hatch-vcs`? about cookie

[henryiii]

I've actually partially started on adding a true/false choice, vcs. It just turned out to be quite a bit of work to add it to all backends at once, especially some that don't support it well or at all. I removed trampolim a few days ago to help, and I might drop whey. The problem currently would be meson-python; I'd like to get dynamic-metadata finished so we can try adding it there.

Cookiecutter supports bools now, and in copier, it can be really nice with when:. I'm thinking about proposing __when__ to cookiecutter. Then I could just hide the option when it's not supported. :)

Ah, good to know this is already being worked upon :)

I see, not every backend has a corresponding vcs plugin or library. The last time I was here, the only method to run cookie locally was cookiecutter, but everything has evolved a lot now.

Let me know if I can help in any way! Feel free to close this issue, or generalise it for every backend.
