@Joey D. - Not a good example, but i think i see your point, you can say that http header spec went through some kind of change, but that change is still confined to a "path" in a well-defined and stable HTTP Architecture. An Open-Closed design allowed the evolution of http headers without breaking the overall architecture.
What we have today in UI are companies partitioning the once simple idea of making a page into proprietary ways to make a webpage, ignoring the spec body and producing their own, which is not all necessary (VDOM) and is actually quite profitable for companies like [name here and here] to increase revenue along just another venue by way of "talks" and shows, and events, video, training and popularity.
Hey, you have all the right to innovate.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
