I think down this route lies code readability and maintenability
madness. Right now, the optimizer and executor code is already a very
complex beast. We don't need to make it more difficult to understand
and improve.
Besides, the guys not updating their applications would not be
benefitted by the upgrade if they kept the compatibility with the older
version, so why would they upgrade?
