ST_DumpPoints overlooks points

=> SELECT path, ST_AsText(geom)
FROM (
         SELECT (ST_DumpPoints(g.geom)).*
         FROM (SELECT 'GEOMETRYCOLLECTION(
          POINT(11 11),
          GEOMETRYCOLLECTION EMPTY,
          POINT(22 22),
          GEOMETRYCOLLECTION EMPTY,
          POINT(33 33),
          POINT(44 44)
        )'::geometry AS geom
              ) AS g
     ) j;
 path  │  st_astext
───────┼──────────────
 {1,1} │ POINT(11 11)
 {6,1} │ POINT(44 44)
(2 rows)

Doesn't seem like correct behaviour since points before GeometryCollection are not included in resulting set.

You think this is worthwhile backporting to at least 3.1?
