Read the comments. The back-and-forth between Dan Abramov and Benny Powers is very enlightening (at least for someone like me who doesn't follow Web standards and library internals closely).
I used to be skeptical about Web Components' ability to impose common standards [0], but I've recently become fascinated with Polymer (LitElement [1] and lit-html [2], specifically). There's even a Redux mixin for LitElement components. Were it not for React Native, I would be giving Polymer much more serious consideration for my go-to technology.
