Part of the premise is incorrect.

Olympus has given us lens designs which attempt some physical correction for aberrations, while Panasonic has chosen a different optimization in its lens designs, specifically leaving higher levels of chromatic aberration present in some lens designs, and choosing to correct this in-body with software, something Olympus does not do.

The above is simply wrong, or at least overstated. Olympus m43 lenses all employ software correction. What they don't provide is software correction of CA, but the definitely make use of correction for other aberrations. And Panasonic lenses don't rely solely on software correction. Their lenses could be much simpler in design if they did, and they wouldn't need the expensive glasses and aespherical elements if they weren't doing optical correction as well as software.

Whether Olympus lenses have more optical, and less software, correction than Panasonic lenses depends, I suspect, on the specific lens(es) being compared.
