I have reviewed draft-ietf-sidrops-rpki-has-no-identity-05. 

It seems obvious that the WG needs to develop consensus whether or not a document such as this, which essentially says "REALLY don't do what this other RFC says not to", is a useful and appropriate tool. If no such consensus exists we can stop reviewing revisions and save time.

If we assume that the document is useful and appropriate…

- In section 2, the title "The Bottom Line" doesn’t seem appropriate.  Could this be expressed a little less figuratively?

- In section 2, the phrase "If it tried to do so, aside from the liability, it would end in a world of complexity with no proof of termination, as X.400 learned." leaves me blank. If we assume that this is likely to make sense to others likely to read this, disregard this.

- In section 2, the two MUST assertions in successive paragraphs are a little puzzling. Is the second a proper subset of the first (looks like it to me)?  If so, does it need to exist? Maybe it's trying to be an example, in which case it should say "e.g." instead of "i.e."  If it's really an "i.e.", i.e. a restatement of the first MUST, then why does the first MUST need to exist?  Also, I found the second MUST hard to understand (reminder: not an expert in this domain, feel free to disregard.)

And, since this is the second time I've been asked, I do have a philosophical unease about this document.  Whenever there is a key-pair, there is an identity in play: The entity which can arrange for documents to be signed with the private key. Which in this particular case, means the entity which has at some point in time could generate ROAs.  This draft implies that there could never in any conceivable world be a useful result of having confidence that some document was signed by whoever it is that at that point in time could generate ROAs for some INR out there. Not the “owner”, not the “controller”, just whoever it is does the ROAs. How can you know that that could never be useful?  In general, when a protocol element or online resource can be used to do something, and someone comes around saying “but you shouldn’t want to do that thing”, I get nervous.
