AFAIR In Maven 2.x it was possible to put anything in scopes and it was very error prone because any unknown scope was silently transformed into compile scope In 3.x the choice was done to strictly check the scope with ones known by Maven. I agree that an API to declare new scope using extensions may be a good thing but the problem we'll have to take care of the behavior to load such extension when maven find such unknown scope and how old versions will manage them.
