If i-Nav leaves its users exposed to phishing attacks, and the users are
bothered by it, then I would expect them to switch to a different IDN
plug-in. isc.org released an alpha3 version of such a plug-in a year
ago, so maybe that could be whipped into shape quickly.

I agree, but in this case, we have already missed the start.  If
we introduce a whitelist now, after IDN deployment is already well
underway, we are effectively punishing an unknown number of innocent
early adopters, which seems like a betrayal.  If we had forseen this
problem, we could have set up the whitelist in the beginning, and
registries & registrars would have known to get themselves added to the
whitelist before making any promises to their customers.
