Making the default transition be specified by an attribute would be good I think! Force transition names would be a good option I think. But what bothers me is migration: A lot of people don't have transition names today nor do they tag the default transition. How can they easily migrate? But I agree: Enforce transition names and enforce "marking" the default transition would be both good in my eyes.
