 In we_use_microdescriptors_for_circuits() we return
 {{{
   !server_mode(options) && !options->FetchUselessDescriptors;
 }}}

 So if you're a relay, even if you don't otherwise cache dir info, you end
 up fetching and using old-style descriptors rather than microdescriptors.

 This decision has a minor effect on bootstrapping, where we won't build
 circuits until we have the full set of old-style consensus-and-
 descriptors, so e.g. time_to_try_getting_descriptors in main.c is dictated
 at that point by LAZY_DESCRIPTOR_RETRY_INTERVAL even if we don't have much
 of the microdesc info.

 The decision has a larger effect on bridges, which fetch and use normal
 descriptors -- over time they will diverge even more from normal client
 behavior.
