Dear all

The only change I foresee in the unaware leaves draft is the addition of the RFC 8505 ROVR from the ND EARO into the DAO. After that I'd feel ready to call for WGLC.

The proposed change enables to build a full EDAR message at the root, and avoids the weird processing of the keep-alive EDAR (see https://tools.ietf.org/html/draft-ietf-roll-unaware-leaves-02#section-7.4)
If we do it now we can forget that weird format (all ones RIVR) and never code for it. This may also be useful when we work on securing the DAO using the AP ND proof of ownership all the way to the root.

Please let me know if there's disagreement to make that change

All the best

Pascal
