"Abstract character" is defined in https://www.unicode.org/glossary/ as follows:

"A unit of information used for the organization, control, or representation of textual data."
(ISO 10646 does not appear to have a definition in its clause 3.)

I'm not seeing a conflict between that definition and my view that a diacritic,
preceded by a letter, can be viewed as two different abstract characters.
I agree that the alternate viewpoint "single abstract character" is not
in conflict with the definition, either.

What is your statement "are not considered abstract characters of their own"
(which seems to leave little room for alternatives) based on?
