Wow this wasm-kernel thing looks interesting. Not sure yet how this gonna help with kernel tasks beside drivers written in wasm (which is nice on its own), but I think they might find a way to bridge the kernel/userland ring issue in a secure way.
About broadway Gtk - lol wasnt aware that this is even possible with Gtk. I have no clue about wayland internals, at least with good old X it would be quite easy to embed "foreign stuff". Broadway Gtk though does quite an expensive roundtrip - where a 3D acc. desktop/GUI would directly paint into the GPU with all its super fast bells and whistles broadway-gtk seems to render stuff in CPU offscreen, moves the view diff through a socket to the browser where it gets merged into the current view (again CPU). Imho a better approach for a wasm/browser engine driven DE would be to use offscreen-canvas and just clip the content into the right place. Lol macusers gonna cry for their battery life :) Well just some random thoughts on this...
