That's an over simplification -- one (applicable to most people) cannot simply
take 19.xx code and roll it back to 17.xx code -- there has been way too many
changes from 17.xx to 19.xx.  If you had compared the code, you would have never
said that.  IMO, 19.xx is better than 17.xx - no question.  I would agree that
the issue of 18.xx is better than 17.xx is up for debate.
