I think you should put as much as possible of the mouse/gesture stuff into your module, so that usual things would work out of the box and we'd avoid duplicating code in each app. As an app author, I'd expect to decide myself what a double-tap results in, but implementing should be as easy as defining "onDoubleClick", where I have access to both pixel and geographic coordinates. I assume those who want to do full custom things can just use MapboxMap without MapboxMapMouseArea, right? Maybe you can also support disabling individual events, similar to acceptedGestures?
