They are in disagreement, AFAIU. The Unicode Character Database (UCD)
doesn't define ß and ẞ as a case-pair: the latter down-cases to the
former, but the former doesn't up-case to the latter. So it is still
a "special-casing" situation (and AFAIU different languages have
different views on its usage).
