I've been reading it more thoroughly too: it would seem entirely within the philosophy of RFC3066bis to permit fr-boont, noting that it is sufficiently useless that it won't be used. (i.e. fr-boont is a contradictory description and hence is a description of the empty set of texts ...). I see nothing wrong with such a philosophy, it doesn't lead to logical confusion, it is certainly easier to administer than the old philosophy (every tag is useful and describes a non-empty set of texts).
