Quite right. Still, is it a *requirement* that IDN not allow punctuation 
and symbols other than ones that would clearly confuse users (such as 
things that look like ASCII periods and things that look like ASCII hyphens)?

How about:

IDN need only support DNS names that consist of characters normally used in 
words and names. These characters MAY include punctutation and symbols. IDN 
names MUST NOT control characters. The IDN protocol MUST specify which 
characters within any allowed charsets are not allowed in IDN names.
