this "not settled issue" concerns only the {-ta'} and {-choH} (when they co-exist) at the same verb, or does it extend to all kinds of verb suffixes ?

It's a question that involves many suffix combinations. Even those suffixes that explicitly modify other suffixes (e.g., -be') sometimes seem to modify entire verbs or entire sentences.
