Description

... because guava event bus doesn't allow cascading events, ie one event to trigger another event.  Instead, there seems to be some sort of batching.

In contrast, axon works the way one would hope, so this should be the default.

Also, in v2, we will probably introduce implementations for CDI and for Spring (on their respective platforms), so we don't really need so many implementations.
