You folks *really* need to go read the news.software.nntp discussion about
xBin. The reason not to use Path, or for that matter anything other than
message ID, is because you want something that you can filter during
CHECK/IHAVE, and relying on your upstreams to pre-filter before sending
you the feed is a nice idea in theory and a lost cause in practice. Like
it or hate it, and I mostly hate it, using the message ID solves practical
real-world problems in efficient and significant ways, and the other
proposed solutions kind of... don't.
