I have already opened up SUB sockets, so that on the JS side can connect as a SUB socket to a PUB - do you mean allowing the JS side to connect as a PUB? In its current state, people who connect as a SUB socket have the option of passing in a msgfilter in their authentication data, the rationale being that you might only want to authenticate certain users to listen to certain types of messages.
