What did you do?

In the context of a CI script, reviewing the changes being proposed in a PR, for example:

$ gorelease -base=vcs:$(git merge-base HEAD origin/master)

I'm spitballing with the vcs: prefix above

What did you expect to see?

A comparison with the HEAD of the master branch. In this case I would expect the VCS reference to be resolved locally, rather than via the proxy.

What did you see instead?

No support for using VCS references as versions.

gorelease should eventually be able to refer to any version that go mod download can accept. So it should take latest (#37410), master, HEAD and whatever else.

Using the local VCS would be valuable, but it's hard to get it right, depending on the scope.

My first prototype of gorelease did exactly this, but it added a lot of complication. It requires copying and modifying a lot of code that cmd/go uses for direct mode. I don't expect things like Git submodules or git smudge could be supported without specialized code and probably a lot of bugs.
