It is easily stated. My suggested wording was Except possibly when relaying to other hosts on the same site, every injecting, relaying, or serving agent that accepts an article MUST update the Path header field ....
Not better, in my view.1. It seems to indicate that "hosts" can be "relays" without being agents. Can you explain?
2. How is this a statement of discretion? Your wording is a narrow exception to a MUST. That makes it more likely that they add them, doesn't it?
3. I like Harald's pendatry on this one. A server farm could be a mixture of NATing firewalls, load-balancing routers, front-end NNTP caches, multi-cast relayers, backend servers attached to NFS, archive storage boxes. All of these are hosts. I think that introducing "host" is not going to bring clarity.
