[as112-ops] Request to add service.arpa to AS112

[jabley at strandkip.nl]

Hi Kim,

Part of the motivation for RFC 7535 was to avoid the need for reconfiguration of AS112 servers for sinking DNS traffic to new parts of the namespace, recognising that this is almost guaranteed to cause lame delegations.

Do we know why the requirements for SERVICE.ARPA is not being implemented using DNAME? Is it too late to ask, or perhaps to suggest that DNAME is the preferred way to do this?
