I'm tapped to do the part about evaluating what we have, but somebody else would need to assess what we need.

To add a bit more context to this ticket: At the April 4 anti-censorship meeting we discussed how to move forward with this:

  • We should ask the metrics team what information is available for bridges.
  • The anti-censorship team should then decide if we need more information.
  • If we decide that more information is needed, we'll create core Tor tickets to collect this information.
  • Nick also suggested that we defer this task until PrivCount is even farther along.

For the lazy, here's an example of the type of information reported in extra-info bridge descriptors:

@type bridge-extra-info 1.3

Removing the "BridgeDB" component because this has nothing to do with BridgeDB.
