Given the trouble that we have every release with trying to cram
everything our users want into a limited space, I'd rather the damned
thing not install than pull in a bunch of packages we don't need, just
to satisfy a dependency that isn't even used during execution of the
package.

Pretty much, yeah.  The main difference that I would see from the
current *DEPEND variables, besides what was said above, would be that a
lack of visibility wouldn't stop the package merge.  If sys-apps/foo had
ODEPEND="dev-libs/bar" and dev-libs/bar was masked, it simply wouldn't
be installed.
