It's perfectly fine to discuss the way things "should be" -vs- the way things "are", but when a design is more than 20 years old, as in this case, then the way it works now is, by definition, the way it should be. Making some changes is just too painful.
An obvious exception has to be made when the way it works now conflicts with some new behavior, that was unanticipated by the original design, but I don't think this is one of those cases. Bob Bolch
