[note well]
How does that differ from my second point ? You
said "nope, on both counts".
It means that reuse of what you write isn't limited
to "might be adopted in an IETF standard if it's a
good idea" - you may also (to give another example
of reuse under 3978) see your words quoted in someone
else's posting that explains why what you wrote is
not such a good idea after all, for instance :-)
That's fair use, we're not yet at the point where I'd
need a patent lawyer for a flamewar, asbestos suffice ;-)
