Realize, though, that just grabbing a frame buffer is not a thing anymore. To render graphics you need GLES support through something like ANGLE, vectors and fonts via Skia, Unicode, etc. A web browser has those things. Any static binary bundling those things is also gonna be pretty large.

And JavaScript is very good at backwards compatibility when you remove the churn of frameworks (unfortunately Electron doesn't guarantee compatibility quite as far back)

And CPUs are only sand powered by electricity.

I do realise the need for abstractions and they do exist, provided there is actually the interest to learn them.
