People are familiar with case-insensitiveness in hostnames in URL.
They often type in WWW.AOL.COM with CAPSLOCK ON inadvertantly even 
after they saw lowercased advertized hostnames and
have been successful so far in reaching the right webhost for
LDH ones and will be so even for future Cyrillic IDN ones.

If they experience failure at the first attemp to visit uppercased
NEW script IDN webhost from the old nameprep browser, 
may of them will guess the webhost does not exist, and
will give up trying another lowercased new script webhost from their
past experience of case-insensitiveness in hostnames.
