It sounds to me like a sensible thing to do.  The only thing I'd like to 
see is some measurements of the performance impact (after all, objects 
are creeated at a furious pace).  Then, if the performance impact is 
measurable, figure out a way to optimize it to regain speed so that it 
is never necessary for someone to override the default just for the sake 
of performance.
