I think it would be the best if the cursor would change the shape of the
cursor to reflect the position of the character within the
composition. forward/backward-char concept should go over one diacritic
at a time.

The way I see it is that a diacritical is just a character by itself -
in case that it is in a pattern that matches a composition, the *display*
is different.
Notice that the composition patterns can be quite long. The maximal
theoretical length I expect is letter+ 5 accent. One practical example
can be found in Proverbs:31:13 5th word "Kol" you have the base letter
kaf together with qamats, dagesh, geresh-muqdam and revia.
An additional aspect is that we should like to add is that we need to
prevent "illogical" composition such as aleph+qamats+patah. reordering
can help detect such cases.
