PR Checklist

Overview

The old logic (introduced in #4543) only handled a subset of cases and caused false-positives.
We probably should have asked for more test cases on the PR to help validate? 🤷 Hindsight is 20:20.

This new logic should cover more cases by comparing the types to a tighter degree.
No doubt there will still be some false-positives here, but without the proper type relationship API we're making it up as we go...!
