I think it would be nice to be able to label (and filter) PRs & issues, and to have some insight before even reviewing changes as to how they impact SemVer. There are a lot of issues and PRs that have already been submitted and there's little context to them on real or potential impact to SemVer.

I opened this in part to help to understand impact of an issue, say #66, which I assume to be major at such time as they're actually removed.
