Yeah; I first heard about this from a German speaker who was complaining about it. He said that you could mangle 99% of English Grammar — no problem. But! you get the order-of-adjectives slightly wrong, and a native English speaker will look at you like you're from Mars. His second complaint is that the rule is rarely taught to native English speakers, such that they (we) don't even know how hard of a rule it is.
