Hiya, > > TLDR: I propose that we allow adding types anywhere in code if it is useful.
+1 I think our current type hints have served us well so far, and I don't see reasons to explicitly disallow them from private code. So, I'd be in favor of gradually adding more hints to the parts of the codebase that see the most churn, while still keeping it optional for non-public API. - Chandan
