I'm impressed that, in the meanwhile, Google has already thrown into the grave not one, but two different implementations of Material Design in the web: Material Design Lite [0] and Material Components for the Web [1], bot of which never managed to actually be competitive UI libraries.
edit: Actually, they've thrown a total of _three_ implementations into the grave, as MWC is in maintenance mode already [2].
