I agree.

Yes, it is different, but there are some subjective similarities.
I've never been under attack from above, but running from the riot
police and tear gas while recording is something I've had to do a
few times (in the Nagra era - they had quite solid rotary gain
controls).

A 1/4 inch steel axle can take a lot more abuse than any linear
fader I know of... unless the potentiometer is supported only by
the PCB, in which case that will be the part that gets destroyed.
But you are right, the essential advantage is that a rotary control
provides support for you hand, you can easily hold it without turning
it even while being shaken in all directions.
