To me React clicked because it was basically PHP or a template engine, just on the frontend and it rerenders when necessary. You can treat it mostly like that, even if it is more complicated. Where signals get into trouble (I think) is when the structure of the elements change a lot, and that's when I'd expect bugs in DOM manipulation or state handling to show up. You also need to remember to listen to these signals, otherwise you have something that updates fine under certain circumstances and not others.
