I think 373k is actually a lot, especially if you consider that "killed themselves" could refer to both "they (singular) killed themselves" and "they (multiple people, e.g. a cult) killed themselves". I think it's more common in British English already, so like you I hope it spreads and becomes more accepted in American English as well.
