Right.
In my case, I was using the nphysics library, which for unsurprising reasons uses Rc for entity handles.
Similarly, in my app's code, I used nphysics' proximity and contact handlers to watch for events that indicated a change in status. Those handlers needed to initialize/set values in a HashMap accessible (and periodically cleared by) the main sim loop -- 'one central thing' that is Rc'd.
It's not sprinkled everywhere in your codebase, and for obvious reasons most libraries don't need to use it. But in applications, a central loop + library-provided callbacks + some Rc'd state of doesn't seem too uncommon.
