I think that this is largely good.

I don't like how the IANA registry is structured and would like to discuss it more.  I think that it is 0-31 (Standards Action), 32+ (Specification Required), but it doesn't say that.  I think that the experimental range (64-79) should not be reserved.  That's relatively valuable space that is being effectively burned forever.  It is also highly dependent on judgment of experts, which gives those experts far more say in the use of the registry than is typical.

(It also says that the registry is initially empty in S2, but it then defines a flag.)
