Is the Backbone dependency absolutely necessary?

I have a project need that polyplayer fits to a T – except that I don't want to use Backbone. Is this dependency really necessary?

Well, you could remove Backbone as a dependency but I don't think this makes it better since we had to implement events, etc on our own. I have thought about this earlier, too, but came to the conclusion that removing Backbone is going to make maintaining Polyplayer harder.
Is there any particular reason why you want to remove Backbone? Polyplayer only relies on Model and Collection, so you could remove Router, History, Sync, etc. to save space.
