Comment(by nickm):

 Okay, so here's a possible plan to do what Roger prefers:

 1) Implement a patch with an option to disables serving V2 directory
 information entirely.

 2) Try a test network where there are v2 authorities, *and* clients and
 servers running older versions of Tor, with that option.  Try enabling
 that option for a subset of the v2 authorities, and for all of them.
 Monitor the load on the authorities, and the behavior of the clients, to
 see if anybody's hosing anybody else.

 3) If that doesn't explode, merge that patch into master, and have the
 remaining v2 authorities try it out all at once.  This WILL require
 coordination, so that y'all can turn the option off in a hurry if it turns
 out to DoS the network in a way we didn't anticipate.

 Plausible?
