so, i agree that destroy is a better name, but since the context is remove: `removeRegion`, `region:remove`, I wonder if this event should bee `before:region:remove`...

It'd probably make sense re-evaluating the naming for a subsequent breaking change. I could see, `destroyRegion`, `before:destroy`, and `destroy` being good substitutes. 

My fear with being inconsistent is trying to remember which is which.
