I suspect most rabbonim truly deserving of these honorifics would prefer to be referenced simply by their names w/o all the adjectives. For some reason, we can reference a gadol hador by his first name (aka R’ Moshe, R’ Yolish etc) or by a sefer he has authored and everyone know who we are addressing without prefixes Gadol hador, saar hatorah, hagoen, ha’rav etc.).
