Exactly! MILCs for more than casual use have the same problem that has limited the adoption of AR (augmented reality) and VR (virtual reality). Lags of more than maybe 5 to 10 milliseconds tend to create discomfort in a significant percentage of users.
For photographers that spend a lot of time looking through the viewfinder, the frame rates of both the sensors and displays aren't high enough. Moore's Law can help on the display and processing side by miniaturizing these components. But Moore's Law can't do much on the sensor side. By definition, a full frame sensor can't be miniaturized and still be full frame.
