Old description:

New description:

 During the entry guard discussions, we have decided that it's a good idea
 to make all relays directory servers. We mainly needed the entry guards to
 be directories, but it seems easier and more elegant to just turn all
 relays to directory servers.

 This is easier nowadays than in the past because `BEGIN_DIR` makes it so
 that directory servers don't need to have a separate DirPort open.
 (However, maybe relays get the `V2Dir` flag only if they have a DirPort
 open?)

 Also, since all relays have all the directory documents anyway, it doesn't
 further bloat their disk to become directory servers.

Comment:

 asn opened #12597 as a dupe, but I think that description is better, so
 stealing it. Adding needs-proposal because I think this will need a change
 in the spec.
