Review Comment:
I ran into some testing issues and after a couple days sleeping on it, it
100% needs to be removed.
Edit: I recall now the issue. The issue is that the new type generation
introduces unsupported types (supported in subsequent PRs), which puts me in a
bit of a chicken and egg situation. But I'll work at this today and see if I
can come up with a more elegant solution that is low surface area, and ensure
the final PR that would eliminate this issue removes anything specific added.
