Comment (by asn):

 Hmm, I took another look here and drew the various diagrams and I did not
 find any cases where your suggestion causes problems. However, it's been a
 while since I last carefully thought about these reachability diagrams and
 I'm afraid whether I'm forgetting something. I'm also afraid because I
 remember a conscious decision for requiring a live consensus, but perhaps
 that was invalidated when we switched to 24hours overlap periods...

 I think your suggested change makes sense, but if we are to do it I think
 we need to implement the new cases in `test_reachability()` and
 `test_client_service_hsdir_set_sync()` since we are basically creating a
 few extra scenarios here that we should make sure we are handling
 gracefully. Also, I'd like to test the branch a few days on my tor browser
 using a bridge to make sure that nothing goes weird before merging
 upstream.

 Cheers!
