Do you have a solution in mind? While a platform (OS) can provide a UI toolkit and provide a HIG, one cannot stop language and programming tools vendors or programmers from doing whatever they like.

I'm starting to think that it would take replacing basically everything that's happened on Web frontend development since XMLHttpRequest with an alternative system that's still standards-based, platform-agnostic and Web-centric, but designed from the ground up as a GUI toolkit instead of a markup language for hypermedia formatting.

Because with the current status quo, the platform that dominates everyone's mindshare is HTML/JavaScript/CSS. Which has a really rudimentary concept of UI controls, and human interface guidelines that spend 90% of their effort on begging people to manually implement usability features that we used to get for free with native GUI toolkits. And I think that we might need to get away from that mess before it's possible for anyone to have any energy left over for worrying about HCI on the level that we used to in the late '90s and early '00s.

But realistically, you’re never going to stop a motivated app designer who is dead set on making their app an unique snowflake art project rather than a tool that users need to use.
