Doesn't seem to matter to investors nor consumers, so why care =) Baby formula has been around for long (I don't think it's as good as mother's milk, but seems geared towards "complete nutrition as far as survival goes, as best as we know today" --- same as Soylent then), ready-to-drink raw eggs have been around for our entire pre-history (but who likes to make a mess, that'd be too primal), etc..
