[tor-dev] Reducing initial onion descriptor upload delay (down to 0s?)

[Ivan Markin]

Hi tor-dev@!

Moving the discussion on the future of rendinitialpostdelay from ticket
#20082 [1] here.

Transcribing the issue:
> At the moment descriptor is getting posted at 
> MIN_REND_INITIAL_POST_DELAY (30) seconds after onion service 
> initialization. For the use case of real-time one-time services
> (like OnionShare, etc) one has to wait for 30 seconds until this
> onion service can be reached. Besides, if a client tries to reach
> the service before its descriptor is ever published, tor client gets 
> stuck preventing user from reaching this service after descriptor is 
> published. Like this: Could not pick one of the responsible hidden 
> service directories to fetch descriptors, because we already tried 
> them all unsuccessfully.

The questions are:
  * Can we drop this delay? Why?
  * Can we set it back to 5s thus avoiding issues that can arise after
removing the delay?
  * Should we do something now or postpone it to prop224?
