URLs are already case-sensitive. Do you claim that users are confused by
this---so confused, in fact, to justify the costs of making all URLs
case-insensitive? Where are the studies supporting your claims?

The careful approach is to start with (1) case-sensitive IDNs in which
(2) uppercase letters are prohibited. If it turns out that users really
need case insensitivity, we can add it later, because of #2. Otherwise,
we'll avoid huge implementation and deployment costs, because of #1.
