Shutter being closed as the lens is off is an awful idea. One misaligned lens or adapter or one slip of a finger and your shutter is gone whereas an open sensor would've been fine as it'd be burried significantly deeper and much better protected by the light baffle around it.
And it's much cheaper and easier to change a sensor glass than a shutter. Also keep in mind that a scratch or dust on the sensor is not really such a big issue while a damaged shutter is.
