They are in fact, used for point-to-point links. It allows someone to
build a kind of distributed router; Kind of like the old IBM remote
bridge arrangemets. Those had either a token ring or ethernet card and
a WAN card of some kind (usually SDLC or X.25) connecting them
together. Kind of cool in a weird, expensive sort of way.
