I totally don't understand how the process works here. This PR doesn't reference a valid issue. The issue that it SHOULD reference (#12455) hasn't been triaged yet, has no lead assigned, and there's an ongoing discussion there about what the best approach is.

Why is there sometimes draconian enforcement of process and at other times it's completely ignored?
