That being said, if they're optically identical, I'm certainly not going to pay a premium for an older MF lens when the AF version is still a very solid lens.

The two lenses are definitely not identical, even though both have 10 elements in 9 groups. The older, MD, version has a more compact design with a smaller front lens while the newer, AF, version has a prominent front lens. I've got no clue regarding differences in optical performance but I guess that the AF has less vignetting (bigger front lens...) and most likely a generally improved sharpness throughout the frame.
