there is nothing that prevents manufacturing of tiny digital cameras with FF sensor other than cost.

Actually, it's lens design.  Film doesn't have microlenses or care about the angle of light hitting the image plane.  Digital sensors do -- simply look at a cutaway of the RX1. See that huge lens element right in the back near the sensor plane?

I agree with most of your post, but not this. The big rear element in the RX1 is similar to the big rear element of the Olympus XA; it allows a shorter lens for the focal length. It is about compactness, not ray angle.These elements cause the rays to be oblique. This was a big problem with digital but lately the manufactures have learned to offset microlenses to compensate. With a single lens to design to oblique rays are no longer a problem. ILC cameras still have an issue because different lenses hit the sensor at different angles.
