I think the correct answer really depends upon what you are trying to do. Sometimes where board space and cost are not an issue people use a combination of larger and smaller bypass caps to reduce switching noise. I don't think there is a one size fits all solution because people power many different types of things from USB. It's more just a caution about USB power in general. Most people know the 500mA current limit, but in-rush compliance is something you don't really see in functional testing because typically you can get away with a violation and the board will still work.
