It would be helpful if section 4.2 (IANA Considerations creating the
Encoding Indications registry) said it was recording the assignments made
in RFC 8949 section 8.1, and adding the _i indication. It would also be
helpful if that sentence noted that _i is defined in the ABNF appendix, as
otherwise the reader is left going "what is this and where did it come
from?"
