Signals are basically lazy functions. You can't "just" use functions if performance is a concern, cause that's the least efficient way to keep everything consistent. Since watching seems(?) to be synchronous in the proposal, why do you think extra debugging tools are needed? You can breakpoint into render() with a regular debugger and look at the stack trace.
