The release-branch-semver scheme appears to match what we do in Matplotlib pretty closely. Since we make tags like v1,2,3, our branches are named like v1.2.x. This unfortunately is not treated as a release branch because of the v prefix in the branch name, even though the v prefix is dropped from the tag.

Now, we've never made a release branch with setuptools-scm, so this is something we could change, but it'd require updating a bunch like docs, CI, etc.

Does this make sense to handle this prefixing in the release-branch-semver?
