The worry is that this will cause subtle bugs when code assumes 
functionality is present.  We tried yanking this entirely and it's 
obviously caused some issues.  The question now is whether to follow 
through and accept an incompatibility or put back sufficient 
compatibility to enable legacy code to work unchanged.
