I thought I vaguely remembered somebody somewhere making ẞ a standard
upcase, but it seems I remembered wrong.  They only say that it's "also

"According to the council’s 2017 spelling manual: When writing the
uppercase [of ß], write SS. It’s also possible to use the uppercase
ẞ. Example: Straße — STRASSE — STRAẞE"
