Lots of failing checks here 😅

yeah, until #231 is merged... a bit circular, #231 will fail one of the dev tests until this merges, and this will fail basically all tests till #231 merges, so 🤷🏻

[jdhoffa]

Makes sense. Will merge #231 first in that case.

[jdhoffa]

Ah nevermind, I see it's already merged.
