Yeah. I debated that myself. But in the end the singleton won.

It's just a cheap global, since is ubiquitous throughout the entire
application, does behave like a singleton, and is a bit too expensive
to create. A full map in the main application takes 3 or 4 seconds to
instantiate and occupies around 2 Mb of memory.
