Re: [Last-Call] [secdir] Secdir last call review of draft-ietf-ipsecme-qr-ikev2-09

To make sure we mention the NIST PQ Level categorization (that will not
change as the NIST PQ Project progresses), I was thinking we could add
something in the Sec Considerations section like 

   [...] Because of
   this, the user SHOULD ensure that the post-quantum preshared key used
   has at least 256 bits of entropy, in order to provide 128 bits of
   post-quantum security.  That provides security equivalent to Level 5
   defined in the NIST PQ Project Call For Proposals [NISTPQCFP].

I don't think mentioning the NIST competition is useful. Per definition,
that is incomplete preliminary data.
