You have conflated two communities here: those who have characters added in Unicode { 4.0 | 4.1 | 5.0 | and 5.1 }, and those whose characters will be added after Unicode 5.1. The former group, which is large, is taken care of automatically by both IDNAv2 and IDNA2008. The latter group, which is presumably much smaller, is take care of automatically by IDNA2008 and manually every few years by IDNAv(>2).

Again, that is (I believe) taken care of with both IDNAv2 and IDNA2008.
