I'm not sure what you're saying. WASM can definitely get access to those things through javascript shims. A native OpenGL ES program can be compiled relatively easily to WASM because it maps one-to-one with the WebGL API and barely needs a shim at all. This has been supported in Emscripten for a while now and makes it a lot easier to do things like port mobile games over to the web.

Yes, this is a more detailed version of what I said. Which part makes you want to control what other people make?
