well, some people do this and think it's really cool that it "works". Esp
when their NS has been delegated a reverse Class C and they try to
re-delegate the Class (rather than delegate two /25's).
DNS is so weird and opaque to most people that I strongly recommend doing
DNS delegations in the most strict, conservative, correct manner. The NS
authoritative for the parent zone delegates to an NS authoritative for the
child zone.
If you can't do the delegation correctly, another approach is to leave the
current NS as delegated, and make it a stealth slave to the other NS as
zone master. The admin of the stealth NS manages the zone data, but the
current NS serves it. This works, of course, for any zone, both forward and
reverse.
