Still, the experts have decided that the best approach is to just deny use of plain TCP sockets and require a specialized protocol.
Maybe in the future there will be plain TCP socket support, but I wouldn't wait. It's really not as important as you might think. Even Flash applets still usually use the "proprietary" protocol via XMLSocket rather than the plain TCP socket feature. XMLSocket is pretty similar to WebSockets in terms of socket, albeit different in protocol.
