As you hinted at I think there are still cases where mass automated card creation is useful. I’ve had success doing this for Chinese characters - I ordered them by frequency and then made them into cards using the AnkiConnect API addon, then I feed in 5-10 new cards per day. There isn’t much creativity required in creating the cards since all the characters have definitions in Unihan.
