 Replying to [comment:3 jeremyfelt]:
 > My only use case so far has only really been for a shaky
 `switch_to_network()` system. I've spent some time thinking of how else it
 could be used or when it would be likely for a primary network to ever
 change. It would be interesting to hear some other possible use cases. I
 guess sunsetting an entire network and firing up a new one could be
 interesting.

 For Happytables, we're using networks for each whitelabel instance we
 have. The main network is our own one, which has different behaviour from
 the whitelabel platform. We're also loading in things like the super
 admins from the main network regardless of network settings to simplify
 the behaviour there.
