As far as I’m aware the only delegation to AS112 newer than that is the home.arpa delegation (RFC8375 [1]).   The reason home.arpa is listed specially on the ops page, and empty.as112.arpa isn’t, is that ‘empty’ is in the AS112 RFCs and home.arpa is off on its own in the Homenet document, which was published more recently.

The problem we were trying to solve in RFC 7535 was that there was no good way to add zones to AS112 servers, and adding delegations to them in the blind was a recipe for lame delegations which seemed messy. Although many AS112 server operators talk to each other here and are well-coordinated, there is no way to ensure that this is universally true and it's a difficult thing to measure in practice.

For HOME.ARPA, RFC 8375 section 7 calmly ignored all the work we did in 7534 and 7535 and even invented a new term "blackhole servers" without mentioning AS112 at all. It's not my favourite.

Although, at the moment I’m not able to put my hands on any piece of documentation that says that explicitly.  Perhaps someone can point out why I’m wrong about that, or suggest that I add that document to the as112.net <http://as112.net/> home page.

The one true authority as far as I'm concerned for delegation to the AS112 servers is RFC 7534.

However, anybody can redirect any zone they like in the namespace following the scheme described in 7535. That was pretty much the point of it.
