True. In a typical production environment when you add on the rods, rails, mattebox, and follow focus mechanism (who is ever going to trust this contrast detect only AF in in any sort of professional work?), being small here doesn't count much anymore. As for casual use, is any small and compact L-mount zoom available to go with this? Does the back screen even tilt? No sensor based stabilizer? Then good luck to ever find a lens with a reasonable balance with the body that has a IS system in it.
I honestly don't think this camera can go very far.
