|I think it would be adequate and sufficient to replace the words ”normal

Sigh, maybe i was mistaken with Switzerland, says wikipedia. I am
too lazy to get up and look into the Duden.
Yeah, Switzerland do not have the es-zed: we have "Strassen", so also no
need of its upcase.
Some old signage may use it, but also other "modifiers" (like the the
macron on consonants), which probably should also be treated in a
special way for uppercase (and sorting). But possibly there is no fix
rule (language, region, epoch).
In any case, I do not think we should rely too much on stability
guarantee, or better: it is necessary for Unicode (especially
normalization), but cases are almost formatting things, and so I think
they may need to be adapted in a display stage, with more information
(than Unicode could deliver), and for sure not stability (rules and
expectation changes).
