Grails 3.0.1 - Multiple event consumers

With Grails 2.x and platform-core plugin we could send an event that was consumed by multiple consumers. Event consumers could reply to the event and the original sender could collect replies from multiple consumers.

I cannot find a way to do this in Grails 3.0.1 so I created a trait that add this feature to my controllers and services. It works for my use-case, but I wonder if this is a common requirement and thus should be included in grails-plugin-events as a standard feature? Or is there another/better way to do this?

It would be great to get feedback from the Reactor guys on this topic.

Here's my trait: https://gist.github.com/goeh/b33363550de083ef541f
Feel free to comment and modify my implementation.

See discussion here: https://groups.google.com/forum/#!topic/grails-dev-discuss/gFZch37urpY

Start by reviewing the linked trait and the Google Groups discussion, then inspect the current grails-plugin-events behavior and its Reactor integration. The scope is to determine whether multiple event consumers and collected replies should be a standard feature, and to document an agreed design or alternative approach before implementation.
