I agree with you.  Thats the way it was intended to be.  But there is 
also an assumption that programs would handle the error appropriately.  
In the real world thats not the case - which brings us again to:

http://www.theregister.co.uk/2003/02/05/dud_queries_swamp_us_internet/

The root of the problem as we can see is that in the real world error 
can result in 98% of your root getting bogus queries.  From a technical 
point of view thats not good.  The ICANN / IANA root zone is under 
significant stress when it comes to error traffic.  And that of course 
is the result of internet expansion in the name space.  As more and more 
people figure out ICANN is a hoax, as have the China MII root people, 
and these people begin running their own root servers - more and more 
errors re showing up in ICANN name space. 

If the metrics in 2003 were at 98% error at the roots then I speculate 
today they will be in the 99.9% range.  Unfortunately I can not prove my 
point because the root server operators no longer share their root 
server traffic logs.  In fact I have seen no root analysis of any kind 
since I wrote up my observations on the CAIDA report on the root servers.

So you see wildcards address error in the name space effectively.  As do 
other methods - like root servers prividing answers to localhost 
queries.  That would significantly reduce the load on the root today.
