Because as far as I can tell, GhostScript - at least the version I'm
running - simply does not have any such capability.

Not if the engine that's interpreting the PDF doesn't have the relevant
primitives, which I think is the case here.

I don't think GhostScript supports the relevant primitives.  If so,
they've got the tiniest Java VM I've ever seen tucked away there
somewhere.

Every GhostScript version I've tried.  I'm currently at

AFPL Ghostscript BETA RELEASE 8.30 (2004-05-29)

which is nearly two and a half years old at this point (I fetched it
2004-06-26), and it basically Just Works for me, but this is not new;
at least one previous version did PDFs too.

If that were what I meant, that would be a reaosnable point.  But it's
not what I meant.  The docs say that GhostScript handles PDF natively,
and everything I've seen jibes with that.
