@limpbrains Any reasons why we wouldn't merge this sooner rather than later?
I can help w/ reviewing, though IMHO it's more like if the CI works then things must work 🤷🏻

It did not provide any noticeable speed improvement that I was hoping for, only adding complexity. I will revisit after we get a new Mac for testing.

Gotcha, I agree w/ your point though :)
Maybe worth revisiting if now that we're on new RN speed differences are more obvious 🤔
