It's like going back in time with Flash Player, There were many WYSIWYG flash based editors around 2010. The problem was it required a browser plugin but it did work much better then HTML4 at that time. For canvas rendering no plugin is needed. Even there was a feature to export SWF file to canvas.

There are some issues like accessibility, browser features like search or text highlighting, lazy loading etc. What HTML provides out of the box must be implemented from scratch.

Padora box was already open the day, WebAssembly and WebGL came into the browser.

You can render in canvas with JavaScript only, no WebAssembly nor WebGL is needed.

Naturally, the point being made was about Flash.
