Document how authorities choose relay status flags
#8273 (moved) and #8435 (moved) are confusing in part because we don't know what they're trying to do. We should decide what they ought to do (starting I guess with deciding with what we think they did), and document that in dir-spec (or somewhere else that's appropriate). That way when we find something weird looking, there's a way to decide whether it's a bug.
In an ideal world, in retrospect, this topic probably could have used a short proposal.
