We match the Unicode specification, not arbitrary language rules. (Austrian and Swiss German are, I believe, phasing out ß altogether, and haven't added an uppercase variant.)

Until the Unicode consortium change their case conversion rules, it is still correct for .upper() to convert 'ß' to 'SS'. The eszett is just one of the many annoying anomalies in case conversion, like Turkish dotted and dotless i. Natural language is hard, and messy.
