Web accessibility for 2019

> Does your web app use chemistry ring formulas or math equations or anything else from any other subject you can think of? So, you can definitely describe all those symbols and formulas to your friend, so your friend can understand those, right? Thus, you should be able to express those in accessibility concepts as well. You may want to practice on your own to see how it goes.
But why those five concepts in particular? Philosophers have been attempting to identify a set of universal groups for human concepts since the ancient Greeks, (it's called "ontology") and I see no reason to think that the author happens to have solved this problem.
For example, what's the difference between a state and an attribute? Is an action a relation between the subject and its object? If an object can change roles, is that a state change? Or is it a change in the relation of the object to its role? Is a role change just an action?
All of the author's proposed accessibility concepts mush together when you think about them critically.
In contrast, WAI-ARIA, taking the problem of taxonomy seriously, did not attempt to define five core accessibility concepts and apply them to all of human experience. They have a zillion different roles, developed more or less organically, to address specific UI use cases.
ARIA's complexity isn't just an unfortunate fact of history; this is literally the best that humanity can do. We can't simplify the world into five kinds of concepts, and it's not worth trying.
Agreed, the state concept (or even role concept) can be technically mapped into attributes, but I keep using them just to stick closer to existing terminology.
When it comes to ARIA, all browsers map ARIA taxonomies into desktop APIs, and thus I think it's fair to say ARIA is mapped into those concepts as well.
But this post wasn't an attempt to define accessibility concepts as such. It was rather about answering a question, whether a large set of accessibility problems can be solved, if the web came with a technology that provides greater access to express semantics to web devs.
None of the relevant vendors are on board, because they’ve all considered a simpler taxonomy and rejected the idea, in favor of a richer, more complex system that can actually be implemented.
Still, the promise of a more text descriptive web is exciting.
IME making JS optional, putting text descriptions, and preserving keyboard access to all features is much lower hanging fruit.
So I'd be cool to have something more powerful and flexible than ARIA is to not limit web devs in choosing the techs.
But building a website and simply not adding unnecessary Javascript in the first place? Far less of a challenge.
What you tend to see with video games is that people appreciate games that have a lot of configuration and control options. That let's the user figure out something that works for them. Unfortunately, that's not going to be expressible with some metadata like HTML attributes.
The consistent theme I see is being able to change the controls, which is often game specific, making it difficult for the browser to help out.
