Most importantly: OP is right re: vanilla example is most legible. Reading the proposal, I have no idea what this "Signal" word adds other than complexity.
Less important: I really, really, really, really, am reluctant to consider that is something that needs standardizing.
Disclaimer: I don't have 100% context if this concept is _really_ the same across all these frameworks.
But frankly, I doubt it, if it was that similar, why are there at least a dozen frameworks with their own version?*
Also, I've lived through React, Redux, effects, and so on becoming Fundamentally Necessary, until they're not. Usually when it actually is fundamental you can smell it outside of JS as well. (ex. promises <=> futures). I've seen 1000 Rx frameworks come into style and go out of style, from JS to Objective-C to Kotlin to Dart. Let them live vibrant lives, don't tie them to the browser.
* I know that's begging the question, put more complex: if they are that similar and that set in stone that its at a good point to codify, why are there enough differences between them to enable a dozen different frameworks that are actively used?
