Comment(by pramsey):

 Rather than adding another semantic for EMPTY WKB polygons, can we morph
 this case into the "standard" WKB representation for that case, namely, a
 polygon with a ring count of zero and nothing else? (Would do this by
 having this case return "true" in the lwgeom_is_empty() function).
 Incidentally, does the wkb_in code handle the one-empty-ring case
 correctly (construct an empty polygon?)
