Again, there's no such thing as "feature parity" because some (many?) of React features are not required by other frameworks.

E.g. you don't need React hooks because Preact has signals: https://preactjs.com/guide/v10/signals/

Does this mean that Preact doesn't have feature parity? For a very strict definition, no it doesn't. Does it mean you need to sacrifice anything? No.

Same goes for many other frameworks. In modern landscape when it comes to features and abilities React is actually quite a poor offering.
