I've more often passed over people for being overly specialized than the opposite. For example, I expect anyone that knows a "modern frontend framework" to be able to learn the others. HOWEVER, if someone has ONLY done React I assume (based on many previous experiences) they will be unwilling or unhappy using something else (Angular / Svelte). If they look like a fit otherwise I'll probably still do a call with them, but I'll be looking to prove they're very openminded and not stuck in their ways. Anyone that is married to a specific tech/language/etc is sus to me. Note, this is just an example, it is not specifically an attack on react (although it is currently a common framework that people get married to).
