Position is a convenience today and in theory can get the same behavior more
efficiently by having your own RefPtr/offset pair and use PassRefPtr as you
like. There’s no PassPosition.

But the more that Position becomes an abstraction that does fancier things than
a RefPtr/offset pair, the more the lack of a PassPosition becomes a problem.
Maybe we need a PassPosition.
