That is true, but it isn't really the point. Emacs can efficiently check many face attributes because it does not have to go looking for them in a list of other things. By contrast, Gerd found that the number of different text properties that the redisplay code needs to look for was crucial to the efficiency of redisplay. Perhaps someone could find a more efficient way of handling numbers of text properties. I don't know.
