Hello Alex,

I support most of the comments from Björn. Some additional comments below.

First, I'm worried that an IESG statement (of whatever content) will 
only complicate things for applicants and reviewers/commenters. IESG 
statements seem to work well for things that affect people who are 
already in the know, insiders,..., but not for outsiders.

I don't understand what's the purpose of this. One of the main changes 
in RFC 4288 was to get away from the fact that every type in the 
standards tree had to be an RFC. This was discussed e.g. with W3C, and 
made it considerably more straightforward to register types from W3C.
For details, please see
It could easily be seen as a step back.

Also, please very strongly consider that while for somebody on the IESG, 
writing an ID, in particular if it only contains the template, is 
something they can easily do before breakfast, for people from the 
outside, it's something where they have no idea where to start, which 
often means they don't start at all.

Can you give any examples? I don't say there are none, but I couldn't 
come up with one myself.

Does that imply that the underlying format should be included in the ID? 
That would definitely deviate from BCP 13.

Anyway, giving clearer explanations (and probably discussion) about when 
exactly and what for an ID makes sense seems to be much needed,
and the actual need should not be just because the datatracker cannot 
handle anything else than drafts.

That's true, and doesn't hurt mentioning. If we say something about 
this, please include a line or so saying that the post should contain an 
actual copy of the registration template (not just "it's over there") 
because that makes it much easier to comment.

Regards,   Martin.
