That shouldn't be expected to pick up a change to make 006C+00B7 collate
like 006C 02B2! (It may, because the notation used is different, and I
think this does affect the arrangement of the data.) I think it also
wouldn't pick up a correction of U+A7F8 from plain superscript to
uppercase superscript, though that would only change a parametrically
tailored collation - and that's a type of change I'd overlooked.

allkeys_CLDR.txt only shows casing if it truly derives from the
tertiary weight, and from the tertiary weight alone.
