Comment (by twim):

 Replying to [comment:2 asn]:
 > I think the plan here is to remove the delay for now, since the current
 30s delay is useless. So having no delay is the same as the current
 situation.

 Yes, we do want to remove this delay (#20082 and tor-dev@ thread). But
 there is code that claims that it works certain way while it doesn't. This
 ticket is to make it work as it should and supposed to.
 So we have to either drop thus dead code or resurrect it (my patch).
 Resurrecting will break our lovely assumptions about how descriptors gets
 published.

 > If in the future we want to add a random delay for security purposes,
 someone should write a proposal with security analysis.

 See ticket description about saving this behavior as `torrc` option.
