I think what they mean is: if you see a line like `import git.example.com/foo/bar/baz`, that could be package `baz` inside module `git.example.com/foo/bar`, or it could be package `bar/baz` inside module `git.example.com/foo`.

Also, even if you know it's the latter, package namespacing isn't strictly related to directory structure, so `bar/baz` has no specific meaning outside of the context of a go import. They could have used any other separator for package components - `git.example.com/foo:bar:baz` - but instead they chose the slash, making the scheme both technically ambiguous and easy to confuse for an HTTP URL.

Ah that makes sense. I think Go did somewhat stumble a bit in the early days due to this, especially with repositories in GitLab, where GitLab allows essentially a directory tree where your repository can be nested indefinitely in directories like `https://gitlab.com/mygroup/subgroup1/subgroup2/repository`.

I still don't think this is a huge issue, to be honest. Not one big enough for me to complain about, for sure. But it's definitely not ideal.
