You have a good point about doing zero copy transferables which would probably work.

There is certainly something beautiful about your charging GPU code being part of a file that runs completely isolated in another thread along with our websocket Data fire hose

Architecturally that could be something interesting where you expose a typed API wrapping postmessage where consumers wanting to bind the main thread to a worker thread could provide the offscreen canvas as well as a stream of normalized, touch and pointer events, keyboard and wheel. Then in your worker listeners could handle these incoming events and treat them as if they were direct from the event listeners on the main thread; effectively, your library is thread agnostic.

I'd be happy to discuss this on GitHub. I'll try to get to that today. See you there.
