Basically this has been the only way to stop anything from happening. But major systems all have accessibility like web and if someone wants to support accessibility they will do it there. Those who don't, won't even do it on web. If something like I say happens, not only accessibility will be lost, but so much more will be lost too. But then if you need it you'll either implement it or use web. Figma, SketchUp, and Google Docs have their software rendered on a canvas. For them this would have made things much faster. It is giving people options. Personally I hate web. It is horrible to write software by manipulating DOM and having to work with CSS. Every time I touch html/js/css I think why can't it be a nice system? Why I have no control over rendering? At least I would have loved to have an alternative the whole web and dom, and would have killed for writing web pages like a flutter app.
