I see for Bitbake appends and prepends are overrides flavor. I still keep my position, generally there is no override component in appending and prepending regardless which life area is considered. Nothing get overridden by appending and prepending. Things just get appended or prepended. I see it to be unlucky these two to be treated in scope of overriding. It is misleading in case of these to talk about overriding.
