The article suggests why 1:1 won't be adequate, there will still be interpolation when the position isn't on a pixel boundary. In practical applications the reduced color gamut isn't a problem, your ability to discriminate the colors goes down as the transparency goes up. It would only be a problem if you were trying to convert the pixels to something less transparent than they started.
