To me it would be most logical to put the correction data in the lens, exactly as you say if it was in the body you would constantly need to update the firmware every time a new lens came out. Well, each time you buy a newer lens at the least.
I don't see an issue with the varying aspect ratio sensors as the image circle is still the same. How you crop that image circle doesn't change the lens distortion and subsequent correction.

A wider or higher image will need more correction, the correction in not on pixel level, but on the total image level. You see the same with the same lens on APS-C and on FF (but more extreme).
