Sounds like a really bad idea to me.

The original problems sound like management issues mostly. Why are they 
letting customers who don't understand DNS update their NS records, and if 
they do, why is it a problem for them (and not just the customer who fiddled 
and broke stuff).

Similarly we'll provide authoritative DNS for a zone as instructed (and paid 
for), even if it isn't delegated, if that is what the customer wants.

For as long as one doesn't mix authoritative and recursive servers, it matters 
not a jot what a server believes it is authoritative for, only what is 
delegated. Hence one can't "graph the mistakes" as one would have to be 
psychic to find them.

Perhaps they need to provide DNS status reports to clients, so the clients 
know if things are misconfigured? Monitoring/measuring is the first step in 
managing most things. But I think far more important to find and fix what is 
broken, than to try and let the machines prune it down when something is 
wrong, although I guess breaking things that are misconfigured is a good way 
to get them fixed ;)
