"Is there any real reason to move it?" is the right question to be
asking.  Moving it because it is the last exception to the rule would
be one reason.  Moving it because it makes this or that thing easier
would be one reason.  Moving it because there's no reason not to move
is silly and should be avoided, as much of the rest of this thread has
demonstrated.  There's a constant balance between evolution and
stability and tilting too far on either side of that balance will make
things too painful for some class of users...
