It is good to keep some of them as MUST,
214 Transformation Applied is still a MUST which is a good thing.
However 110 Response is stale should be back to MUST instead of SHOULD, 
otherwise the client doesn't have a way to differentiate the response. 
(but I know that IRL it's almost never done).
One thing would be to require a MUST only when the expiration time is 
_not_ an heuristic one (as in this case, the staleness property is already 
heuristic).
