 automatically.

 Yeah, that's part of this: We need to tell to all dirauths that are
 running the external guardiness script that they should stop running it
 (including you) since it's not gonna be used any time soon. We should
 probably email the dirauth mailing list or something.

 (BTW, wrt "we never did" to tor, we did that once 3 years ago and that's
 how we learned about #16255)
