Generally I'd agree with banning control characters by default from pathnames in a new OS, but it's too late to do that now with Linux/Unix.
I don't think it's too late at all. The overwhelming majority of legitimate filenames do not contain characters in the range proposed for blacklisting. As an option that's turned on by default, forbidding control characters would present no practical problems whatsoever. Nobody relies on filenames containing ^V or newline.
