In fact this seems to be the only reason that RFC 3172 requires a
zone cut between the root and "arpa" (and possibly between "arpa"
and "in-addr.arpa", although that is less clear). Section 2 lays
down that the operational requirements for the "arpa" nameservers
have to match those for the root nameservers, precisely because
they are to be a different set.

And in section 4 we read

|  Currently, the "arpa" zone is located on a subset of the root
|  servers, and the zone is managed in accordance with these
|  specifications.  The IAB is working with ICANN, IANA, and the
|  regional registries to move "arpa" and "in-addr.arpa" records from
|  the root servers in accord with the RFC 2870 recommendation for
|  exclusive use of those servers [5].

This was published over 8 years ago, and it hasn't happened yet. Are
we really expected to believe that this is still work in progress?
Rather than an old idea that seemed to make sense at the time, long
since abandoned?
