Of course yes. My reply was largely tied to the parent's description of a date-picker component. But for application level components I'd use event names that are unique at the application level that conveys the intended semantics of the event. Everything else becomes an argument to that name, which pretty much aligns with your notion of instance Id et al although I'd be less rigid about the particular structure of the arguments.

although I'd be less rigid about the particular structure of the arguments.

My reasoning was for conpatibility and consistency. If everyone makes up their own argument structure, it becomes very difficult to maintain and puts the onus on the developers to remember which components use which structure. I'm not really asking for much beyond standardising that the first argument of an instanced event of subscription query is the instance id.
