That's a good point. But, given the "look-alike" problem, and 
comparing it to the possibility that an upper-case Omega may appear 
within a name, what's the "better" solution?  You can't have both.

I'm not arguing just for the Omega glyph (that's just an example), 
but rather I believe that there are more than a single glyph where 
its uppercase may present a better solution for a "look-alike" 
problem than it's lowercase counterpart. And, I am not proposing a 
mixed case solution for the IDN, but rather a single case for each 
code point. Granted, the vast majority of code points would remain 
lowercase, but a few uppercase exceptions may alleviate the 
"look-alike" problem.

Just an idea.
