 Replying to [comment:29 dgoulet]:
 > @twim, yeah you'll need a Gitlab account, sorry about that but it's
 worth it. If you had more commit, I can add them to that branch so we
 don't lose our discussion.

 Sure, I prefer to move review-specific code to something ephemeral to not
 litter trac.


 > Removing `proposal-needed?` as we don't define upload delays in the
 specification only time period HOWEVER I found this in rend-spec.txt:

 (cf.

 clients.

 Sure, it's really important and somehow I forgot about it. I think there
 should be some __short__ random initial delay __only for on-disk
 services__ since they are being started at the same time (note that this
 code doesn't actually work now). I'll soon update my branch.
 The delay for hiding startup time has different purpose and should be
 treated separately (see #20262 and my branch `obfuscate-startup-time`).
