Comment (by arma):

 Replying to [comment:12 catalyst]:
 > * TODO: check whether it's possible for a single instance of tor to
 download both ns- and microdescriptor-flavored consensuses.

 Yes, it should be possible. Anybody who is a dir cache does it, because
 they want to fetch both of them so they can serve both.

 But a given Tor will only make client-side path selection choices based on
 one of them -- whichever flavor it is set to use. That's controlled by
 UseMicrodescriptors and the associated consensus param.

 One of the challenges is that it's unclear which use case we're trying to
 cover here, and they at least somewhat contradict: telling the controller
 about new directory objects, or telling the controller about information
 that we're going to be using for our future circuit choices.
