Dear Nick,You may have misunderstood that phrase. I was not referring to the fact that there are no standardized normalization forms for Unicode (I explicitly mention Annex 15 in [1]), but to the fact that there is no standard that specifies which of the possible normalization forms should be used for account names (and other fields in passwd).
POSIX explicitly limits itself of a subset of ASCII, so it is not going to mandate any normalization form. Are there other standards (or initiatives) in this area that you know of?
