Hi Alexey,

>Thank you for addressing my comments. Unfortunately it doesn't look like my DISCUSS point was addressed yet. 

Correct. There was a slight misunderstanding between the authors. It seems like Suhas thought all issues had been addressed in my pull requests, which was not the case. Sorry for the confusion.

Our plan is to go for option c), and create a new IANA registry. We will create a pull request, and verify that the WG is ok with it.

The text already says that "Specification Required" applies to new entries.

I am not aware of another registry where we would define entry-specific rules.
