Thank you for bringing this proposal. Overall it looks very nice - it saves us a lot of engineering effort to check nulls, and is a stronger convention that could be adopted in the codebase.
I am more concerned about the upgrading plan. As for now, nullable ObjectRef is still allowed, but some day in the future is behavior will be changed. A clearer timeline will give us a better idea what to upgrade and when to upgrade :-) --- [Visit Topic](https://discuss.tvm.ai/t/allow-non-nullable-object-and-introduce-optional-t/6337/4) to respond.
