Is this an argument in favor of checking for prohibited names in client
applications?  Today's client applications don't check for prohibited
names (like a+b.com), and this hasn't led to any catastrophes.  Today
canonicalization and prohibition are both performed on the server side.
Nameprep proposes to perform both functions on the client side.  I'm
suggesting that a less drastic change (performing canonicalization
but not prohibition on the client side) may be sufficient, and even
preferrable.
