Then there are are DOM APIs like <canvas>, SVG APIs, etc ... each of those would either have to be disabled on worker threads or take additional work to make thread-safe (even if the additional work is just checking code). There's also styles and subresource loading, which we already disable on XHR data documents but I'm not sure if that's defined in any spec. Basically this is a very big can of worms you're opening here...

We all, like sheep, have gone astray, each of us has turned to his own way; and the LORD has laid on him the iniquity of us all."
