The Observable proposal made a stronger case in my opinion, since Observables provide an interface that is functionally unique and useful for the boundaries between app logic and libraries, so a single standard approach has benefits. Signals on the other hand live right where application state binds to the ui. Is this really somewhere that people are patching together a hodge podge of libraries that need to use a consistent api? I'm not so sure.
