The root of drive C: is, indeed, spelled "C:\".  However, the spelling "C:"
has a well-defined meaning, and it has since MS-DOS 2 when directories were
introduced.  It means "the current directory for C:".

Because it's not an exception.  The meaning is well-defined.  This can be
very handy, for example, when copying between deeply nested paths on
different drives:

    cd "\Ridiculous\Long\Path\Names\For Annoyance"

    cd "\Another\Ridiculous\Long\Path\Name"
    copy C:one.txt D:two.txt
