But RFC 8067 updates BCP 97 now gives us flexibility to do the right thing:

   The process in RFC 3967 is hereby updated to specify that explicitly
   documenting the downward references in the Last Call message is
   strongly recommended but not required.  The responsible AD should
   still check for downrefs before sending out the Last Call notice, but
   if an undetected downref is noticed during Last Call or IESG review,
   any need to repeat the Last Call is at the discretion of the IESG.

You're welcome.

Quite possibly so; and, yet, we have made a distinction, and we should
either eliminate the distinction or honour it.
