Having worked in the Semiconductor Industry (Eng'r Mgr) for 40+ years, I think that mfg. COST** of a larger sensor is the biggest problem followed by increased software issues. Also, the internal needs of the camera would be different.

...you think the cost of sensor 25% larger than APS-C would be the largest problem?  I wonder what an APS-C sensor costs compared to an mFT sensor, as APS-C sensors are 65% larger.

** Mfg cost includes the decreased number of sensors on a wafer as well as the yield (which decreases dramatically with chip size.) After production testing also increases with chip size.
