I'm excited about this development. I'm really looking forward to a web implementation of Material Design that is not bound to Angular 1 and is production ready. I did a few projects using React + Material Design that was enabled by Material-UI component set. [0] And although Material-UI seems like a really great implementation for React, it's certainly not production ready yet. I did spend a significant amount of time fixing / messing with its code to make things work relatively smoothly.
Regarding the Google's MDC-Web [1] the demos look promising, although the components seem to lack polish and animations sometimes get stuck. I hope they will push them to the point where these components will be as good as Angular Material ones. [2]
