call at the top of the transpiled code assigned the window object, which obviously already has jQuery, so the selector worked, but is very dodgy. (I think you alluded to this in your talk?)
The intended result is that if you are holding a piece of data, and you have a dep for it, you can ask the global dependency server whether it has changed by sending the key and version. The main benefit of this approach is that the application server doesn't need to be aware of which queries each client is currently tracking - the client can keep that knowledge for itself, reducing the burden on the server and giving the developer more options for controlling when new data is fetched.
