Moreover, familiarity with Greek and Latin is very helpful even when reading English-language texts, in part due to the influence of those languages on English, and in part (I admit this is a bit circular) because English-language authors—especially the more academic-leaning ones—up until quite recently assumed they could toss in some Greek or Latin and their readers would understand it, especially if it was just a quote from some familiar text the reader surely encountered in school. I could see loosening the requirement, but if the loosening isn't simply to permit French and German (also hugely important in academics, some fields more than others, very influential on English, and also often untranslated in otherwise English texts, so, justifiable for similar reasons) as substitutes, yeah, I'd regard it as likely a step backwards.
