Re[2]: Is WebGPU about to be used for user interface rendering

I noticed in recent discussion of the Iced GUI library that there are plans to support the WebGPU API. This raises the possibility that WebGPU could be used to render an entire user interface, bypassing most, if not all, accessibility-related technologies on the Web.
That sounds like HTML 5 <canvas> element, and the resultant shadow DOM 
all over again.

Actually its worse than that, as <canvas> was in a browser that has a 
rendering engine and inherent plumbing that could be used to support 
accessibility.

Hit testing anyone *grin?

In desktop operating systems, of course, existing APIs could be implemented to support accessibility, but besides the Accessibility Object Model - still actively developed? - we don't have an equivalent for the Web, as far as I know.
