TSIG and SIG(0) (not yet covered by the draft) require reversable modifications of the message. I would be appending a new additional record (code TBA) and removing it which contains the addresses. I would not be modifying an existing OPT record. Nor would I be adding a new OPT record. Modifying/adding a opt record requires a lot more, error prone, work to add and reverse the changes to make TSIG and SIG(0) work.
The additional section count would be increased by 1. TSIG / SIG(0) may now be followed by this record.
