This usage is useful only for -S mode. The recent Asian codecs register its aliases by their respective .pth. So, backporting CJK codecs won't let Japanese developers code in this way.

Of course, users may have installed JapaneseCodecs with --without-aliases, in which case the aliases won't be there (neither automatically, nor after explicitly importing japanese). I believe mailman use it that way So people who currently do

encodings.aliases.aliases.update( {"shift_jis" : "japanese.shift_jis"})

would have to adjust their code.

I also find that installing JapaneseCodecs on top of a CJK-enabled Python 2.4 causes shift_jis to use the CJK codec, not the japanese codec.
