It isn't impossible, but it can be unreliable and is problematic for existing 
users of the cupsSendRequest/cupsGetResponse APIs - they have to handle the 
downgrading themselves.

We *did* try tracking the supported IPP version in the first version of the 
patch for this issue, but it didn't work reliably.  Forcing the issue in 
client.conf seemed the safest approach.

Filed as the following bug in Apple's bug tracker:

    <rdar://problem/14216262> cups.org: Missing documentation for ServerName 
foo/version=1.1 in client.conf

(looking forward to getting the cups.org bug tracker back up...)
