Why no in-camera CA correction on Olympus bodies?

My guess is that the CA correction process is Panasonic proprietary and not part of the m4/3 standard like the distortion correction.. Oly could reverse engineer it to work with existing lenses, but there's no assurance that this is future proof.

What if Panasonic invokes a new variable that now gets used in a new lens, and suddenly the Oly calculations get thrown off for that lens? Now they have to issue a firmware update.
