Thanks for the feedback.

I don't think there is any evidence of a "land-rush" and even if there were 
it's fairly trivial to expand the type range.  The thinking behind this 
approach is that as long as there is an open specification, there isn't any 
compelling reason to limit allocations to IETF approval.

The goal is to make it easy for a w.g. to get allocations early in the 
process so people can get implementation experience and avoid collisions if 
the protocol becomes widely deployed.  Having to wait until there is IESG 
approval makes it much harder or risky to do deployment.

While the IANA may or may not have resource issues, the "burden" placed on 
the IANA is fairly trivial.  If the allocations get to the 85% point, all 
the IANA has to do is to ask to IETF to review the allocations.  This 
doesn't seem very burdensome to me.  IMHO we won't ever get to that point 
based on the history with the IPv4 ICMP allocations and IPv6 to date.

Yes, this does mean IETF RFCs.  Paragraph 3. covered non-IETF requests 
including non-IETF RFCs.

Thanks for the comments.  Input from others is very welcome.
