How about something like this:

"Client and server implementations that already support the Brief field 
header should be able to add support for the return=minimal preference 
with little effort."  (I had "minimal effort" but it didn't read right)

"If a server receives both Brief and Prefer header fields in a request, 
it MUST ignore the Brief header field and only apply the Prefer header 
field preferences, if it so chooses."
