That was, indeed, my point relative to the presumably small
audience for tools that take a bit of knowledge and
understanding to use.

Of course, in this situation, "avoid the risky situation
entirely" means either completely avoiding IDNs completely or
learning to avoid any domain name that is not obviously based on
one's native language (and, in this case, I do mean "language").
The latter might easily have the interesting property of
inducing a false sense of security and making easier for the
phishers.  What comes after people get burned that way is
presumably abandoning DNS name guessing and/or typing in IRIs or
URIs entirely.
