The plan is to move the registry from the tcpdump website to IANA and use the 
currently defined values
at the tcpdump website as the initial value for the IANA table.

Once this is done, the table hosted at the IANA website will be the only source 
of truth for this
registry.

Does this make the intention clearer?

<tp>

Yes, that is clear; I do not see any such statement in the I-D.

It also seems to be a giant leap backwards.  The tcpdump website has a mass of 
useful information, 150 or so links to the reference documents for the link 
protocols that it references which could be useful outside the context of 
tcpdump,  while the I-D, and I assume the IANA registry, has not one, not  
single reference - to me that is, well,  a giant leap backwards.
