Comment(by strk):

 lwgeom_add_bbox() does the lazy addition already.
 I've stubbed a lwgeom_get_bbox() function calling the lazy computer and
 returning what it gets as part of r8333 but found out that in case of an
 _empty_ geometry the lazy computer computes a bounding box composed by all
 zeroes. I don't think I like that.

 What's the bounding box of an EMPTY geometry ?
 /me hopes we wont go to BOX EMPTY ...
