What I don't understand is why they chose to put the major version as part of the path part of the uri (/), as opposed to some other separator, e.g. fragment (#). Especially since it's optional. You can always convert "example.com/foo#v2" into the "/v2" if needed, but if you see "foo/v8" is that a repo "foo" version major v8, a subfolder of "foo" named "v8" or a repo "v8" in the project "foo"?
It’s traditional at least with web browsers to not send the fragment to the server. Query param would work, but implies your routes don’t change much between major versions.
Import paths are used to figure out where to fetch the source code from. To simplify a bit, if you see `example.com/foo/bar`, it works because there's an appropriate meta tag at https://example.com/foo/bar?go-get=1 . The import paths are pretty directly used as URLs.
