Hot take: the web technology toolchain is plenty powerful as it is, and expanding it will cause more problems through misuse of newer features than it would create solutions.

Yes, web standards offer loads of tools that let developers and designers get _really_ creative with their work, but we've reached a point where many of us are spoiled for choice, and loads of the mainline options are used, abused, or otherwise ill-optimised to the point of making many websites heavy enough to turn many laptops into space heaters.

Worse still, the "spoiled for choice" factor means that people keep finding radically new ways to use the toolchain; while this is arguably not a bad thing in isolation, it makes it _so_ difficult to keep up with what you're _supposed_ to use at any given time.
