Even two Unicode releases doesn't guarantee that the tables are
correct.  The only proper solution I can see is to stop modifying
published decomposition tables.  When mistakes are discovered, new
character codes with proper decompositions should be added and the old
character codes declared obsolete -- which is option B in the vote,
but unfortunately neither IDN nor IETF has any voting powers (which
suggest a methodological problem).
