Could be. I would really like to find documented verification of this somewhere: What exactly does it mean when the warning light flashes?

It definitely takes much longer for the warning light to start flashing in MDM mode than in normal DSC mode. This is why I assume that when the light flashes controls are ON and when the light is OFF controls are not interfering.

Anyway, when I got the car new MDM was peace of mind. Slowly and carefully I have made the transition to DSC off completely. Now I don't use MDM except when it rains (= rarely).
