 come up with a plan and timeline to deprecate onion v2 services.

 This should be the meta ticket for all ticket that need to be solved
 before we can deprecate onion v2 services.

 * What are the required milestones?
 * What tools depend on onion v2 services?


 (random) tentative deprecation date : 2023-12-31

 maybe announce it as a tentative date so people depending on onion v2 can
 speak up about there needs sooner rather than later.

 The first actual step to v2 deprecation, is to make v3 the default
 version.  But to get there, we first need to solve various bugs and
 issues with the current v3 system (#25552, #22893, #23662, #24977,
 etc.).  We also need to implement various needed features, like offline
 keys (#18098), client-authorization (#20700 ; WIP
 https://github.com/torproject/tor/pull/36),
 control port commands like HSFETCH (#25417) and revive onionbalance for
 v3.  We might also want to consider possible improvements to the UX of
 long onion names (like #24310) (https://blog.torproject.org/cooking-
 onions-names-your-onions).

 After we do most of the above, we can turn the switch to make v3 the
 default, and then we need to wait some time for most of the users to
 migrate from v2 to v3. After that we can initiate the countdown, and
 eventually deprecate v2s for real.

 It's hard to provide an actual timeline for the above right
 now. However, we are currently applying for some onion-service-related
 grants, and hopefully if we get them we will have the funding to
 accelerate the development pace.
