Seems to me like you're suffering from "I can't replicate it therefore it does not exist and everybody else is either lying to me or a complete idiot."

You haven't actually called anyone out as liars or idiots, but your lack of belief of what they are communicating to you and the tone (from what I can gather) of your responses speaks for itself (whether or not that was your actual intention).

So, no "real world" assortment of plugins for today's multilingual developer? Is that a valid assumption?
