The main difference between Clicked and Released signals is as far as I 
know whether you released while-on-the-area or not. If you pressed on a 
mouse area, drag away from it, and then release, you should not get a 
Clicked and only a Released event.

So personally I don't see how you can get rid of the Released event, 
since you wouldn't be able to respond to all releases anymore (only the 
kinds that are Clicked). The Clicked event is the optional one, but it 
provides convenience for a very common scenario (that of a push button) 
so I'd consider it unhelpful to remove it.
