We do use the service catalog, quite extensively—on the client side.

nova just uses the delegated credentials from the user.  Looking up the
service catalog is indeed quite cacheable; however: I don't believe that
such code has been added; it may be necessary to pierce abstraction
boundaries to perform that caching; and the glance endpoint is likely to
be pretty static anyway, and thus fine for setting by means of
configuration.  And again, it has been a while since I looked at that
code path…
