Authoritative servers (listed in NS records) shouldn't be recursive. This prevents leakage of cache data. This provide consistent answers. The server also doesn't have to decide what type of answer to give (recursive vs authoritative). Glue doesn't get overridden by answers, etc.
Recurive servers (honouring RD=1) however can be authoritative for zones. This proves robustness in the presence of link failures. Faster than ttl expiry of local zone changes (provided that notify messages are sent). Unfortunately this has become strict seperation lore which really wasn't ever the intent.
