Okay -- perhaps ludicrous is a more apropos term.
Reality check: ISPs already force renumbering.
And as several people have already stated [deja vu, many times over],
this draft, if moved to BCP, has no teeth. It simply states that the
idea of address ownership is null and void, and Joe's ISP decides to
pull up stakes and move to another upstream provider [B] for whatever
reason, Joe should not be surprised when his [A] provider asks him
to return his address allocation so that its doesn't punch holes in
his CIDR block.
This makes sense to me.
