Not just m43s. Sony/Nikon/Canon, I'd assume the rest of the major brands as well nowadays; most frequently for Pincushion and Barrel distortion. Such corrections are all but essential for affordable zooms, but I'm still split on the potential for over-use in primes. I'll point to the Sony 16/2.8 E as an example; the use of correction in JPEGs is pretty evident compared to shooting raw, and you can see the correction softening the corners.
