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].
Agreed! Given the state of Material Design for the web, I'd ended up rolling my own implementation using native web components via Lit. Personally, I love Material Design and the expressive enhancements they've done, but I was hard pressed to find a good alternative with all the bells and whistles.
