I agree completely, unfortunately some APIs (DOM events being a good example) make this unknowable or at least impractical on a timeline one or more commits forward. At least as far as I’m aware, there are no static analysis tools which can find “events which might reference this”. Which isn’t to say your point is hopeless, just that a better strategy is to comment regardless of known cross cutting concerns and get ready to hope.
