Yup. KoreanCodecs will be retired after CJKCodecs 1.0 is released.
And, I don't have permissions to replace the others because I am not
an author of them.

Comparisons for CJKCodecs 1.0 vs {C,J,K}Codecs:

Implementation  Pure / C      Pure / C         Pure / C       C only

(1) KoreanCodecs supports 'sane' StreamReader for euc-kr, cp949 and johab
    only.
(2) unijohab, qwerty2bul and mac_korean are quite minor encodings and
    ignorable.


I don't think CJKCodecs can replace Chinese and JapaneseCodecs immediately.
But, CJKCodecs will be remain useful in respect of abililty to support
inter-cjk encodings like ISO-2022-JP-2 and ISO-2022-INT-1.

Thank you for your interests! :)
