    The timeline Visual Effect Activation track (or rather it's clips) have the ability to send event attributes which makes sense to me since the api behind both is just SendEvent and that function has that parameter but what would / could you use this for?

    Maybe I am not seeing it but since Stop ends emission whatever one could send through that event would not matter anyway?

    I am asking out of curiosity is there any example where this is used?

    Never used timeline with vfx, so maybe this makes no sense, but what about this?

    Ah yes I see, because otherwise I would need to send two events each: OnPlayA (with attributes), OnStopA(events do not matter), OnStartB (again with attributes), OnStopB (again events do not matter).

    The timeline clip always sends both Play and Stop (because every clip always has a beginning and an end) but if used with other scripts and a setup like that it does make sense.
