IMO you either need to go all in or not at all. And by all in I mean your "web page" is nothing but a <canvas> tag and your non-web framework is handling basically everything. It's an unholy nightmare for many reasons but it would at least allow you to make a reliable self-contained system.

"We'll take your native constructs and jimmy them into some bastardized HTML" is almost always full of razor-sharp edge cases.

Agreed! And indeed we are still considering switching Rio to a Canvas + WebGL/WebGPU. The reason we've decided against it for now is accessibility, and weird edge cases such as Copy & Pasting.

What about text rendering?

Apart from native a11y, hackability/"DX" and affordances like text selection, I feel that text rendering is a big moat of classic web technologies.

How does a screen reader interact with one of these canvas pages?

That would be one of the entries in the "unholy nightmare" bullet list.

Well that but with WebGPU just might work without turning your app into lagtown central, in a year or five when it's widely supported anyway.

I'm old enough to remember making admins with Adobe Flex. I unironically kind of miss it.

What a huge step back for the web.
