 We should write a Tor proposal for the various hidden-service statistics
 that we're considering to add to relays' extra-info descriptors.  That
 proposal will facilitate public discussion on tor-dev@, because we'll have
 a single document that we can edit and improve.  Primary focus will be to
 say whether the suggested new statistics are safe enough to gather.

 Examples (from Roger's recent post to tor-dev@):

  - How many intro points were established at my relay over the past 24
 hours?
  - How many rendezvous points?
  - How many of those rendezvous points got used?
  - What were the various usage stats of the intro points?

 Suggested next steps:

  0. Make a list of suggested statistics.
 [https://lists.torproject.org/pipermail/tor-dev/2014-October/007642.html
 This tor-dev@ thread] already contains plenty of suggestions that we need
 to extract.  Should we add more suggestions as comments to this ticket?
  0. Translate that list into the proposal format with concrete data
 formats that can later be merged into the extra-info descriptor section of
 dir-spec.txt.  We'll want to keep this document in a torspec Git repo.
  0. Do a first evaluation whether statistics are safe enough or not, and
 add those assessments to the document.  This also ties well with (4) from
 the end of Roger's tor-dev@ post.
  0. Polish the document and send it to tor-dev at .

 dgoulet, asn, and I agreed to co-author this proposal.  asn suggests to
 aim for mid-November for sending it to tor-dev at .
