I agree. But you gotta start somewhere. The first step is to just recreate the components.

Have you looked into the polymer elements http://www.polymer-project.org/docs/elements/? I'm not sure if it would be against the license, but in principle they have a complete implementation of the material design that could be extracted as a separate css-only framework.

Polymer is licensed under BSD so it shouldn't be hard at all to do that and comply.
