I might be reading you wrong, but just to err on the side of clarity:
packages that install .pc files do so for the benefit of other packages that
expect to use pkg-config to find them. For example, gphoto2's .pc file would
come in handy if graphics/sane-backends were to use pkg-config to look for
gphoto2.

gphoto2 will use pkg-config to find graphics/libexif if you have pkg-config
installed and comment out the line "CONFIGURE_ARGS+= --without-pkgconfig" in
gphoto2's Makefile.
