Re: Will reverting DNS wildcard have any adverse affects?

Paul, I would not call "root-delegation-only" an enhancement.

it's an enhancement in the sense that it's more complicated and it's more code and it came later in response to complaints about the earlier feature.

With "type delegation-only", you had to specifically name these and only these zones you wanted restricted. With the latter, you need to be alert all the time, keep an eye on all TLDs, whether they are legally using delegations. If I am not mistaken, "exclude" statement to this option had four revisions already.

Four revisions in the first two days, none since. -- Paul Vixie
