There are many Latin script languages that require using one or more
combining diacritics even in NFC.

One problem with Latin script languages, will be languages that have
digraphs as part of the alphabet. If typesetting Dinka or Nuer in
print, and wanting a different style or presentation for the first
letter, I'd e thinking in terms of letters of the alphabet (which
includes digraphs).

Not sure how that would translate to a CSS rule. For instance the word
for Dinka in the Dinka language starts with the letter "Th", not the
letter "T" which is a different letter.

Wether such distinctions can or should be included .... not sure ...
