I agree. Korean compatbility  CJKs are in every day CJK use, but CNS11643 
compatibility CJK  may or may not! I guess they will be rarely used.

Whether or not  full CNS11643 support is rare does nothing to do with
the current issue. In any cases, _if_ someone enters those characters,
he will get errornous results surely! That is the concern.

"Chaos" does not mean stringprep/nameprep is a total failure. For example,
stringprep/nameprep is useful and satisfactory for everyday hangul syllable use!
My concern is that even such partial failures would make chaos _in some
cases_. We can't ignore this. We should do "something", but i am not
sure what to do yet.

As i stated above, whether they are rare/real is not the issue.
Do you agree?
