Yes, Kevin Rooker (who supposedly is responsible for this function) manages to survive every purge. He's a great guy, but do we really know what he does? As for the others, they are clearly useless and survive because their cost is probably low.
Or perhaps these people's purpose is to frustrate the channel to the point where we stop asking Sage to do these things. (""We don't want you to merge. We want you to sell, sell, sell and if you don't, then just leave, so we can sell direct."")
