Reconsider deletability criteria

[jandrieu]

Criteria 36 got rewritten in PR #38, which adds a nice distinction, but loses the point of the original, which was addressing how the desire for actual deletion is addressed, not just the regulatory compliance.

          <h5>Question</h5>
          <p>
            How are mistakes corrected, and how is the right to be forgotten
            addressed? (Note how this creates a tension with immutability,
            which may be valuable in 2.7.1 and elsewhere.)

              Provable deletion of data is fully supported. Once something is
              deleted, nothing internal to the system allows it to be recovered.
            </li>
            <li>
              True, provable deletion is not supported, but deleted data can be
              suppressed in jurisdictions where this is required.
            </li>
            <li>
              The VDR is a permanent, immutable record with no support for deletion of any kind.
