I'm not sure that we are. There now seems to be agreement about the 
long-term solution (add foldrWithKey etc), even if the details of the 
deprecation cycle are not agreed.

So it's clear that removing the deprecation of foldWithKey just for this 
release would only be a short-term measure. Gregory, are you willing to 
accept it on that basis?
