@froucher I've continued my review and pushed some more commits to my feature/handle-properties-of-complex-metadata-types branch, please cherry-pick or merge.

Besides those commits, I think this PR can be merged.

For debugging, running the test suite with npm run test:functional:doing and changing into the temp directory which is git controlled is a game changer!!! 🎆

Well done! 👏 🙏
