Yes, but is this a useful property or not in real LEGO? I think it
just let the axle rotate free and nothing more. Or am I wrong?
And if we see it on MLCad, we can't move the axle so fine like this
"fair amount of movement" since the minimum grid size is 1.

I don't know. If we call it to friction I agree with you.
But I think there must be a rotation properti for the grey
pin, and no rotation allowed to the black one (still connector).
I think it would be the easiest way to handle the pins as connectors.
And over the LCD the LMPL (as the higher layer) will give an addition
properties to it (similarly to the object oriented programming).
How about this?

It seems to me that the difference between grey pins and black pins is structural in nature: they are different connectors from a builder's point of view. I (...)
