The Flux fragmentation makes this hard to talk about. The examples I've seen from Facebook all use global singletons. There are some libraries/implementations that work correctly, but it's hard to know how widely used those are.

I guess the high order bit for me is that developers shouldn't have to worry about stuff like this—picking the "right" implementation of their app architecture. Ideally, everything just works out of the box. The harder it is to do, the less likely people are to do it.
