I'm not sure how much this would increase the load. To look up
www.example.com for the first time, you have to traverse the
com name server. If the com name server simply answered with
www.example.com's IP address, that would obviously save you
the next query and wouldn't increase the load on the com name
If you looked up www.example.com again, after the A RR's
expiration, you'd have to go back to the com name servers. But
you might have had to do that anyway if the NS RRset's TTL
was on the order of the A RR's TTL and had also expired.
