Null/No-op ListenerAggregate?

[weierophinney]

hi Team,

do you see any value in a NullListenerAggregate?

i'm using feature toggles in a production app and would like for my listener factory to be able to produce a valid ListenerAggregateInterface but maybe one that doesn't do anything if the behavior in the aspect is disabled via toggle.

maybe there's another way i can solve this problem that i haven't considered.

thank you : )
