I'm not sure that answer is helpful. If they aren't revving the ID when
features are added, how exactly is someone supposed to know the feature
status of their release? I know they were trying to compartmentalize
features, but feature number is the quickest and easiest way to
differentiate functionality. If you have to filter through a list of
potentially hundreds of features to determine compatibility, that's going
to be a nightmare long-term (which is why most products use a version
number in the first place).
