In case you missed it, here's a good usecase for a new,
user-visible, Bbox type:

An ST_Tile(Bbox, vsize, hsize) could be useful for boxes, and maybe
not so much for Geometries.

Note I guess he's talking about ST_Expand, which we have defined for 
all kind of types, each returning the input type (big confusion as always).
