Well if we found a way to offer some level of modularity and optionality (despite SE or EE 8 not putting a strong emphasis on either yet) I would certainly see it as an option. This could keep the size for some apps down if they use other event systems already.


strictly yes, in practice the event bus is rarely more than few kb so does it worth the time the EG would spend on it?

not sure I agree, SE has an event hierarchy but its listener model is not
as usable as CDI most of the time because of the register side
