AF, freedom from distortion, no requirement for an in-lens leaf shutter like R1.

"No requirement"... huh?

There is little reason you couldn't use a focal plane shutter in a fixed lens camera. Leaf shutters are generally preferred because they are much quieter. They also allow for faster sync speeds. The only advantage a FP shutter might have is a higher overall shutter speed, but even then that is really just an illusion ¹. The two main reasons they're traditionally used in interchangeable cameras is to (a) protect the film from accidental exposure... obviously not an issue with digital... and (b) so that you don't have to equip each individual lens with a shutter.

Personally I would love to see leaf shutters as a feature on some interchangeable lenses; It doesn't have to be on every lens, but in some cases it would be nice to have if only for the sake of practically silent shooting.

¹ Shutter speeds beyond the x-sync are produced by closing the rear curtain before the front curtain has fully opened.
