Yes, we discussed that very issue. Requiring the server to execute the 
PROPFIND if it happens to be cheap is not only bad spec writing (how 
would you do a compliance test?), it also doesn't make sense (in many 
cases, even counting the descendants of a collection will be almost as 
expensive as returning them -- the recursion is the problem!).

Furthermore, servers today already work this way (they are *configured* 
to reject PROPFIND/infinity in any case), and I'm not aware of any 
client problems because of that.
