Thank you for these points. I've made some corrections in the post.

> consider that something like à can consist of either a precomposed "à" code point or an "a" + "` diacritic" sequence

If Unicode provides a precomposed combination doesn't it mean that in fact has a code point for every character? Regardless of offering diacritic combination codes?

From my understanding the precomposed ones don't exist for every character, for latin scripts this might be true but other scripts are more complex.

Simple example is emojies where there isn't a precomposed codepoint for all combinations.
