My point was that it is not a challenge, you simply move the optics further into the barrel if needed, similar to, say 300mm 135 format lenses, for example. Sure, it is a challenge to take full advantage of such a mount, but choosing a short register distance is a no-brainer with no disadvantages.
Of course it's not "impossible", it's just "totally stupid".
No, Sony didn't lie when they said that the E-mount was capable of using an FF sensor. They just happened to forget to tell you that everything you put on that camera (shorter than 50mm FL) will have to have about the same or only very subtly smaller retrofocal ratio as a lens planned for a full DSLR camera...
That means that IF the RX1 was released as an exchangeable lens camera, the 35F2.0 lens that is on the camera now would have to be planned as a retrofocal lens in stead. Think something about 1.5x larger in diameter and 1.5x longer than the existing 24/1.8 for APS. Slightly smaller than the 18-200, if you're going for image quality rather than compactness. If you're going for all out compactness, like the 50/1.8OSS - but a centimeter larger in diameter.
I think that kind of negates the "no-brainer with no disadvantages" statement.
