[idn] The ACE myth redivivus

["D. J. Bernstein" <djb@cr.yp.to>]

It has already been established that some common practices, such as
copy-and-paste for domain names, will be broken by the (horribly
expensive) ACE transition.

This goes far beyond ``leakage,'' i.e., bad displays. Login connections
will fail. Web pages won't be loaded. Mail will bounce.

Dave Crocker nevertheless claims, in his comparison table, that ACE
carries no ``risk'' (and no ``operational expense''). That's the ACE
myth. Are we going to have to tear it to pieces _again_?
