Do we need or want to change these at this point?

Obsoleting is just, well.. obsoleting.  The implementations conforming 
to the old specs aren't going away any time soon.

I guess the proper resolution depends on whether we want the document 
focus on:

  1) what we think the node requirements are now (or were a year ago)

  2) what we think the node requirements should be in a couple of years
     (as nobody is fulfilling them at present)

  3) what we think the node requirements would be in an "ideal world"
     (where only specifications exist, not implementations)

FWIW, I have a document in a slightly similar situation (but still 
different as it's not a requirements doc) but not so far in the 
process (draft-ietf-v6ops-ipsec-tunnels-01.txt).  It covers both IKEv1 
and IKEv2, and both old and new IPsec architectures.  Even though the 
old ones are now obsolete, I'm not going to remove the support and 
text on the obsolete ones.
