Anyway, I do prefer “ẞ” and would also be interested whether there is
a place (CLDR or elsewhere) to propose it. But I suspect that even in
2017, it was not intended to recommend “SS” over “ẞ” and that they
simply added a sentence that dealt with the new capital letter in a
potentially misleading fashion. If they had simply turned around the
2017 wording

“Bei Schreibung mit Großbuchstaben schreibt man SS. Daneben ist auch
die Verwendung des Großbuchstabens ẞ möglich.”

to

“Bei Schreibung mit Großbuchstaben schreibt man ẞ. Daneben ist auch
die Verwendung von SS möglich.”,

you might have a point. This is not what happened, though. They
changed it to a SINGLE sentence about the POSSIBILITY of “SS” (besides
the POSSIBILITY of the (already known) capital letter; and since “SS”
is not a single letter, it is not surprising that it is not already
listed among the letters).
