Certainly, if I were a user registering a label that might be
construed as being in German, I would try to do that regardless
of what the relevant registry required.   But, if the registry
did not exclude mixed-script registrations, I might also
register a label containing β (U+03B2) any time I intended ß
(U+00DF) to appear and vice versa, simply because, in some
fonts, they look a little too much alike.
