triggerMethod is a function called a lot in the Marionette hot pathes. So i am against increasing its complexity. There will be performance impact out of the box for all users regardless if they are using this feature or not

In fact recent changes go in the direction of minimize its usage.

Yeah I agree that, in the very least, any change like this would need to be perf scrutinized to the nth degree. I think the help wanted tag might be misplaced. I think this issue is entirely dependent on the possible replacement of Backbone.trigger if/when that happens.. if/when the Bb API needs to be upheld.

Close this as it is not needed
