I don't think the WG should address this as proposed, because AS112 is
unnecessary:  A delegation of "local" address space to IP Address
127.0.0.1 makes all problems go away.  So, there is no need to have
AS112.  Second, AS112 Approach does not offer any pro-active correction
to the problem of misconfiguration, which is the source of the traffic
AS112 hopes to "sink".

There is a better approach.

The better approach is for the WG to recommend to the in-addr.arpa
maintainer to put in delegations for 168.192.in-addr.arpa et al to be
delegated to 127.0.0.1. These delegation records should have the maximum
TTL.

This approach has two beneficial effects that AS112 doesn't 
offer: 

1) The nameserver operator with the misconfigured nameserver will begin
getting "recursion to self" errors, which will prompt corrective action.

2) The delegation records will be cached on the local nameserver,
reducing unnecessary traffic from the misconfigured nameserver.
