Perhaps not so much on recusive nameservers, but more on autoritative nameservers and caching, I'm usualy having a hard time explaining ISP's they should delete their authoritative zone when authority is transfered away from them. Most ISP's seem to think that a record allways expires in a cache, and it then allways queries the root path for a new entry, instead of only updating the TTL from the authoritative source they allready have in their cache. They mistakenly think they are no longer queried after their former parrent changed the delegation.
