It is possible to have thousands of tests and a lot of blind spots, but it's easier to get a grip on that using instrumentation like code coverage and indeed by using LLMs to prod at edge cases.
I am OK with trusting that it is likely the React team understands how to rigorously test based on how well-tested React itself is.
