It isn't very useful then, and is more error prone than having RDEPEND
in both the second and third case. Plus, errors won't be necessarily
caught, because Portage will treat PDEPEND in the same way as RDEPEND
(unless there would be circular dependencies, but I don't see how that
could happen).

So, simplify and go for RDEPEND (+DEPEND if needed) only?
