That's just taste.

The problem is the following: When creating a file we have
to prove that the file does not exist in a different
upper/lower case combination. Under Unix, the only way to
prove this is to list the whole directory and do a case
insensitive comparison on each existing file.

Doesn't matter. Windows does not distinguish between both.
