Hi,

Thank you Yaron for your comments. Please find the new update ot the draft:

https://github.com/mglt/drafts/commit/0b2696ada172163930f3733a7c3155d49bca0002

Comment 1:
IKEv1 is out of scope of this document. IKEv1 is deprecated and the
recommendations of this documentmust not be considered for IKEv1.

I change MUST NOT in must not. I left the whole sentence as I beleive, it
provides the reason why IKEv1 is not in scope and state clearly that
applying considerations in this document to IKEv1 is a bad idea.

Comment 2:
I added some clarifying text on why not MUST. To me the obvious reason is
that an algorithm not mentioned in RFC4307 should not have a status greater
than SHOULD -- unless otherwise of course ;-). I though we had this
explanation somewhere, but maybe it is missing and should be added in the
intro for example.

I also provided dome explanation why ESP and IKEv2 are in a different race
which resulted in having AES-GCM not widely deployed for IKEv2

Comment 3:
"As it is not being deployed" as been replaced by "as it is not widely
deployed"

"and now it is known to be weak at least for a nation state" has been
changed to "and now it is known to be weak against a nation-state attacker".

Acknowledgement section has also been updated.

BR,
Daniel
