Comment (by pramsey):

 The answer might be a review of the use and semantics of lwgeom_release. i
 don't think it's widely used, so we can tweak it slightly. I think it's
 fair to say the semantic is: "release the container but leave the
 contained". for for a lienstring, it would leave the pointarray intact,
 and for a polygon it would leave the pointarrays intact, but drop the
 rings[] array. And for collections it would leave the sub-geometries
 intact but lose the geoms[]. But possibly it's being used somewhere
 outside that semantic box.
