Well, to get that info, you'd have to do even more shell-foo :)
I believe that KDE-related packages often have dependencies of the
former sort; for example
use imlib && built_with_use dev-libs/imlib X
I've personally encountered use-deps of the type:
use cairo && built_with_use category/cairo X
use avahi && built_with_use net-dns/avahi gtk
etc.
Also, the same logic would apply to the existing pkg[use?] deps too.
However, pkg[use1?use2] seem to be (at the very least) common in
relation to pkg[use?] deps.
