you're making a couple of assumptions that might not be valid for all 

a) the dns services available to a user are administered by their 

b) the local dns services implement their own caching scheme.

in tommorow's world of dialup/isdn/cable from-the-home internet 
connectivity assertion (a) fails. as for (b), many smaller organizations 
run pc-based dns servers which generally do not cache, frequently 
referring rather than recursing queries.

that said, i would think that it wouldn't be the end of the world if a 
client could choose to postpend www hostname resolution results in their 
/etc/hosts (or equivalent hosttable store) if said option was enabled. 
in fact, some people might think it was nice.

a good place to ask this question might be comp.protocols.tcp-ip.ibmpc, 
where some of the less powerful hostname resolution schemes are better
