Also, take a look at this response from 2021:
"Like I said earlier, it was always the intention that we're not going to be able to work on it full-time... [I]t was intentionally designed for this kind of sporadic development. We would get critical fixes out as soon as posible, but overall, starting with 2.0, it's mostly in maintenance mode and does not strive to be the best tool for production React apps. It is a tool to get started and get something running fast. Perhaps, it's not even best at that anymore."
