To compare with the security issues of IDN is more than a stretch. On the other hand, can we be certain that someone someday might not find a way to turn a confusion between e.g. 1996 and l996 in some future client protocol? I'm not saying I'm convinced it's something we need to do. Just raising possibilities.
