I'm somewhat confused about the workings of PCB in this aspect - I
suspect this has something to do with the complexity of rotation etc.
Polygons are (usualy) defined by their corner points. Rotations of
points are
most often done by multiplying with a rotation matrix - so there is nothing
special about general polygons and rotation compared to rectangles or
triangles.
(90° rotations of points can be done by coordinate flipping, but again
nothing special)
Just my 2 cents
