I believe RFC 7534 §2.2 [0]  (listed on that page) is the most up-to-date document on what you need to set up in order to support an AS112 node.   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.

Newer "delegations" are supposed to use the DNAME method, and so shouldn't require new action on the part of operators to absorb queries for them.  Off hand I’m not sure why home.arpa wasn’t done that way.

It’s likely the One True Authority on what might be coming your way is probably the Locally Served Zones registry [2] at the IANA.  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.
