We're working on this tracing tool as we move things like Page Rules and Rate Limiting into the same engine that runs Firewall Rules. Lots of advantages of using the same Rust-based engine/syntax to let customers express their configuration rules, e.g., adding rule-based alerting and combining different types of filters and actions. Focus so far in the design process has been how requests get evaluated against a list of Custom and Managed Rules but if you imagine a world in which everything is a rule (incl. routing to/firing a Worker) it becomes tractable to do what you're asking about. We'll be in discussions with the Workers team about how to best illustrate the handoff to Workers and what happens downstream: cache, origin fetch, etc.
