Describe the feature you'd like:

React 18 alpha is out, our library is starting to determine what we'll need to do to support it. We use this library for tests and I don't see an issue for it already nor do I see a PR for it.

Suggested implementation:

I think just changing over to create is most of the work reactwg/react-18#5
I don't know if this would need the work that Testing Library is doing as well for concurrent mode, I don't know enough about how that works with this. testing-library/react-testing-library#937
