Well it apparently didn't work because even on its own the admin list doesn't appear
No no, it's not actually RTB.
The way RTB prefs work is that they check to see if RTB exists first, then they call the register pref command. So Glass alone would not be able to register RTB prefs to it's system if RTB doesn't exist in your add-ons folder.
So it creates a fake RTB so that add-ons with RTB prefs in them will call their register commands, which register them into Glass's prefs instead.
