Actually it is.  It is the case-mapping of ß which was disputed.
However, unless I've missed something, it still possible to change the
upper-casing of ß to be ẞ. 

When they get encoded, I trust the Arabic crown letters will lowercase
to ordinary letters, but ordinary letters will not uppercase to crown
letters except in one very special locale.
