Comment (by nickm):

 So, one possibility to consider is to introduce another consensus flavor,
 as we did before when we added microdescriptors in the first place.  That
 would potentially let us re-engineer a lot of stuff.  Though I'm not sure
 we can actually drop RSA identity keys from the consensus as long as the
 legacy HS system exists, if we believe that the hash ring needs to work
 like this.

 For the purposes of this ticket, maybe it would make more sense to figure
 out what the probability is for onion service clients/servers to
 upload/download from the wrong place, and look into other ways to
 constrain that.  For example, we could increase the spread (as teor
 recommends), or require that a certain fraction of the network be known,
 or something like that.

 Who knows? It may be that the problem that led to this ticket will go away
 once we've solved the various pending microdescriptor download issues
 (like #23985 and #23817)
