It's probably also worth pointing out that while ranges do compress the data a bit they make it harder to answer questions like "is this register mapped properly" since the question becomes "is the numeric value of this symbol between the numeric values of any of these other pairs of symbols we have listed here". I generally find it harder to review drivers using ranges since when checking that things are mapped voatile or whatever you have to do lookups like that.
