That's not entirely true; consider crossposted articles. If it were just
a matter of pointing to one newsgroup and article number, there are a
bunch of solutions that would work; the difficulty comes in when you start
looking at crossposting and realize that there's no inherent limit as to
how many groups to which something can be crossposted.

Oh, you can get just the headers already; that's part of the storage API.
It just doesn't help; hunting down and opening the article is already too

I think this is what you'd have to do, but it breaks all existing storage
formats since none of them have metadata or a way of holding it right now.
(And you really want to assign a number to every newsgroup, which is
something I've talked about from time to time.)
