It's like trying to make DES safer.

Not at all. They (including some Japanese) just wished IDN
work ignoring technical reality.

Technically speaking, there are several sets of frequently
used different but similar Japanese characters most people
do not distinguish so vigorously.

For example, "Sai" of "Saitoh", the tenth most frequent
Japanese family name, is represented by 4 similar but
different characters, which is distinguished by people
named "Saitoh" but not distinguished by most others,
which means phishing is unavoidable.

That is, RFC4290 covering such Japanese characters is
not technical from the beginning.

It is nothing more than a political statement, because
there is no reasonable way to use tables in Appendix A.

Which means IDN can not be "Internationalized" at all and
selling IDN is nothing more than a fraud.
