I think this contains some misunderstandings. Opportunistic install is
not (mainly) for saving disk space. And package dependencies only is
in my opinion too rough.

The main advantage of opportunistic install is easier structure. It is
basically the same thing as (require ...), but from the network if

Using only package dependencies makes it hard to "announce" new
possibilities. In the case of nXhtml I have tried to announce
possibilities by placing them in menus. If only package dependencies
where used that would mean installing the menus for nXhtml would
install all of nXhtml.
