It's the same issue with the "W3C is just a standard." Rather than making the lives of web developers and users easier by just basing every web browser on Chromium we have to deal with caniuse, polyfills, nonstandard extensions. Basic features like tab sharing are implemented by Google's NIH cast protocol. There's no such thing as a website anymore there's Chrome apps, Firefox apps, and Safari apps. More time is spent wrangling webpack then doing actual web development.
