Sure. But it's not only about being smart, it's about learning from your mistakes. If we are going to talk about reverting to something that was abandonded in the past, it's of paramount importance to learn why it was abandoned as the problems it was thought to be causing back then might very well reappear with it being introduced back into the system.

This is indeed an issue I'm developing a passion about and this type of thing is something we have seen in the past and I did write about it about two weeks ago - The Cobra Effect. In my opinion, we should not consider any changes before we have spent considerable time and effort on thinking about what could go wrong because of the change we are advocating.
