The center should be on the rotation point.
Like you said, rotating the pieces when the rotation point is not centered
on the hinge is a bigger pain than getting the pieces into the right
position.
(It would be great if some future version of LDraw would have a center of
rotation separate from the the physical centerpoint).

I'd rather name them after the function than the shape. So "stepper",
"discrete" or "lock-step".
