ST_SubDivide garden crasher on Polyhedral Surface

[robe]

SELECT ST_SubDivide('POLYHEDRALSURFACE Z (((-72.2 41.755 0,-72.2 41.755 1,-72.2 42.755 1,-72.2 42.755 0,-72.2 41.755 0)),((-72.2 41.755 0,-72.2 42.755 0,-71.2 42.755 0,-71.2 41.755 0,-72.2 41.755 0)))'::geometry,3);

Is this even supposed to work with polyhedrasurfaces. If I give a number like 5, doesn't crash, but gives this error

SELECT ST_SubDivide('POLYHEDRALSURFACE Z (((-72.2 41.755 0,-72.2 41.755 1,-72.2 42.755 1,-72.2 42.755 0,-72.2 41.755 0)),((-72.2 41.755 0,-72.2 42.755 0,-71.2 42.755 0,-71.2 41.755 0,-72.2 41.755 0)))'::geometry,5);

-- ERROR:  Error performing rectangular clipping: IllegalArgumentException: Invalid number of points in LinearRing found 3 - must be 0 or >= 4

So it's trying, whether it should or not is another question
