I'm the author. No data is sent after dependencies have loaded. The "init()" function in the page runs right after. So you can use the Network debugger to see that nothing is sent anywhere.

I just don't think an ugly page can be useful for the layman. It has to be a nice and user friendly page, which means it would have a lot of design loaded as well. Use the "_bare" page if you want to customize it for your needs.
