Existing DNS servers, SMTP servers, HTTP servers, etc. don't treat an
uppercase C-cedilla the same way as a lowercase c-cedilla.
This is why, in both the ACE approach and the UTF-8 approach, C-cedilla
is prohibited on the wire.
If you want users to be able to type C-cedilla and access your c-cedilla
domain name, you'll have to wait for thousands of programs to be changed
and redeployed. I don't want to suffer these costs, and I certainly
don't want to wait that long for working IDNs.

P.S. The UTF-8 encoding of c-cedilla passes safely through sendmail.
