It would be nice to have a button to add a todo without using the optimisticKey, so it is easier to see the benefit of this api.

What feedback does the React team want regarding optimisticKey (and other experimental APIs)?
Some APIs are mostly complete and just need testing for the next release, or for web standards to reach the point where they can be used (like ). Then there are some APIs that edge cases and additional use cases might need to be figured out about (like fragment references).
For optimisticKey it seems like this is an API that needs to be tested before being released in React 19.3 or 20
