John Klensin has raised another concern:
"I'm prepared to lose this one, although, if I do, I'm going to
press strongly for copyright transfers to the IETF so the policy
can be administered ("why that is relevant" is probably a
different thread, but hinges on when an excerpt isn't "just" an
excerpt)."
I'm not sure. If we get the right to allow derivative works by 3rd parties,
why would we need this?
Good question, I don't see why.
In general, I think that Copyright transfers may be a good idea
anyway. It would, e.g., enable the IETF to defend copyright
infringement on RFCs. OTOH, the IETF might prefer to avoid wasting
time in court though.
