I understand that DAD is pretty useless in sparse mesh networks, but is it
worth adding a special case just to avoid three packets every time you

If you've got links so slow that DAD is a significant overhead, perhaps
you should be looking into some generic form of header compression rather
than trying to special-case DAD.
