You know this is not true. This only guarantees that one level of
delgation is exactly the same. For all practical purposes the RIR
proposal does the same.

In no way does this ensure that the answer to a reverse query is the
same for .ip6.arpa and .ip6.int.

We are still waiting for your example about a substantially different
answer which you claim results from the RIR proposal.

And what you mean by

given the fact that ip6.arpa is delegated to the RIRs, and
consequently it is the RIRs who would need to make that delegation,
not IANA.
