I agree with how you've split it but this PR still needs to be smaller.

I'm a few files into this and it's still way too much for a single PR. Each change is "simple" but I'm struggling to concentrate with so many very similar changes to look at. Can we get say, 5 files max? And split the tests into their own PR, I see their utility but they can land on their own.

I don't disagree with what I've read so far though, and I think my only objections are going to be some casts added or removed.
