No.

That would be inefficient, so isn't likely to be a solid implementation 
strategy in many environments. I don't see any reason to do it this way.

That's what regression tests and review are for. Obviously if we rewrote 
the algorithms and introduced bugs and just left them as is, we'd be 
pretty awfully incompetent. Nobody is suggesting that the work will be 
done before we have reached a point where the new spec is as good or 
better than the existing specs.

There's no desire to make the new spec incompatible with existing 
software. That would not be a useful spec.
