I am not a fan of this. Browsers by now have awesome text layout and rendering support, highlighting, screen reading, zooming. Individual images can be seen/copied/saved, user scripts and styles and browser plugins can access the loaded html content, and so on.

All this will have to be redone in canvas for no good reason and I doubt it will be nearly as good as what browsers can do already, and we will lose a lot of openness and interop.

Yep, like this one - https://pbrfrat.com/post/imgui_in_browser.html

Microsoft is already doing it with .NET, others as well.

Expect the revenge of browser plugins.

no way a .net plugin become mainstream, thankfully we left behind java-like-plugins.

Sorry to disappoint you, but everyone is on the WebAssembly race, all plugins will be back, like it or not.

Thank browser developers for opening the pandora box.

While I agree that we may be able to rid ourselves of JS, why would we want to rid ourselves of HTML? It's become an excellent language for describing a UI.
