Ok. Cool and all. But isn't the need for this a hack to begin with? Why isn't there some more unified graphics system by now? When it comes to presentation, the entire industry is fragmented that necessitates these things.
WebGPU is too low level for most users so it needs a framework on top, and that would mean changing the way code distribution works (from bundling to packages) if you want it to be efficient.
Skia is at the right level but then you need to maintain two very different graphics APIs in parallel and somehow make them work together. You can't just give up WebGPU because games and graphics editors are starting to require it.
