The method currently called removeIf is like an atom with one valence 
electron, searching for a pattern to bond with; right now it is floating 
free.  It currently has found a bond with the removeAll atom, but if the 
methods like Map.replaceAllIf(Predicate, BiFunction) existed as 
originally planned (they basically fell off the side of the card), it 
would form a stronger bond with the other xxxIf methods.

Which argues to leave it is as is, since I suspect eventually we'll 
discover that the existing Map.replaceAll is pretty weak.
