Seems like 2.0 is the worst of both worlds: little/no continuity from 1.0 and little/no benefits of starting from scratch.

As for little/no benefits, that is certainly not true. Angular 2 is going to be better in almost every way from Angular 1 and there are many great apps built off Angular 1. If you haven't tried Angular 2, I suggest giving it a go once the they get to beta.
