Mach # gear limitation

Hello all.

As I was looking at a poster of the 744 cockpit I noticed that the gear operation is limited at max .82M (I then saw that many other aircraft have this sort of limitation)

What is the reason for a Mach number as a limitation for the landing gear extended/extention speed?

Is there concern for shock waves forming on the gear? (I guess there is otherwise they wouldn't have put it there)

So my next question is why would the gear develop enough shock waves to be of concern, at a lower Mach than the wing does?

Not sure what the exact Mmo is on the 744, but I'm sure its more than .82M


Thank you in advance for your answers.
