While I've not checked the context yet, this seems to be terrible
wording. The context doesn't direct this towards hosts constructing
packets? What is the 'It' you refer to, the TCP RFC? Do any of the
following override this awful wording job?

RFC1122 / STD0003 Requirements for Internet hosts (comm. layers)
RFC1123 / STD0003 Requirements for Internet hosts (apps)
RFC1009 / STD0004 Requirements for Internet gateways
RFC1812 Requirements for IP Version 4 Routers
RFC2979 Behavior of and Requirements for Internet Firewalls

The last one seems it would have the most potential to clear up this
mess, unfortunatly it's only an informational RFC, and at a quick
glance, doesn't look like it addresses this issue. Regardless, the
intent of the author was clear... it'd just be nice to be able to
quote chapter and verse.

Besides, I'm MUCH more worried about all of .uk being behind an ECN
eating router then not being about to talk to some Microsoft webmail
service.

I fear this problem is doomed to repeat itself as well, as more of
IP's features become unreserved (Class E IP Address, anyone?)
