I listened to the discussion today regarding the proper language to put into the contract regarding Urgent requests.  The components of the discussion seem to be:
These elements do not fit together in any coherent or meaningful way.  Attempting to plow forward is a mistake.  (Law of holes: if you find yourself in a hole, stop digging. -- https://en.wikipedia.org/wiki/Law_of_holes)

It seems to me a much simpler and more effective solution is the following:
  1. Every registrar must have a designated point of contact for high priority situations.  This information does NOT need to be publicly available.  Instead, the information should be available to trusted parties.

    There is little risk involved in disclosing information to trusted parties.  They are identified and accountable, and the disclosure is made in good faith.

  2. Requests and disclosure made via this solution should be documented and reported appropriately.

  3. There is no need for contractual language that sets forth a specific timeline.  The requirement for a point of contact is all that's needed in the contract.
As a separate but related matter, I believe there is similar treatment for reports of DNS Abuse.  If a similar structure has already been agreed to for DNS Abuse, it's puzzling why the same solution is not being used for both purposes.
