Actually, if one is going to do internationalization properly,
one of the most often-cited goals is to permit people to spell
their names correctly.   Since many mailbox local parts reflect
personal names, that principle applies to them too.   And NFKC
eliminates a lot of characters that are needed to correctly
spell names.
