Very much agreed on that one. Usually in the context of
"identifiers" and not in free text.<br>

Differences in how Unicode data is interpreted has open security holes
in systems, and while this isn't particularly likely with this change,
it is possible, which is part of the reason case-folding is guaranteed
to be stable. Such a change can confuse case-insensitive filesystems,
or change the interpretation of code in case-insensitive filesystems.
The automated default isn't going to change, and German is going to
have to join Turkish in that purely default case-conversion just
doesn't work for them.
