I have a similar feeling. I keep up to date on changes to these other frameworks but in my work we've never run into React performance issues that couldn't be fixed by approaching things with good principals. Signals are brought up in convo every now and then as an approach to fix an issue, but stepping back we always seem to find a better solution but just re-writing bad React code. I'm sure if you're on a certain scale of users or extremely custom UI you could run into circumstances where signals would help you, but for our system that serves hundreds of thousands a day, we don't need them yet.
