If you put "UNIMPLEMENTED();" here, you'll get a loud and clear warning
(V8_Fatal) if you ever accidentally try to execute this. That may be helpful or
annoying for the development/debugging workflow you have in mind, so it's up to
you.

Cool. Actually, though I'm pleased enough with this. In the next couple of days
I'll be calling this thing, and I'm happy with it just missing. That way I can
test out components of the vector store pipeline, and this will act as a "pass
through" node.
