I really hope that in further investigation you (JetBrains) realize how futile it is to attempt to automate defining something like this.

The best-case scenario I can imagine is that I have to enter a public URL into the editor that JetBrains can then `git clone` from their server.

I can’t imagine “JetBrains curates a list of all public git servers” ends well. (As a Tildegit user.)
