Which datasheet, and will the system design actually be varying them at runtime - if it will how will it do so? This is the settings for the particular system and generally a lot of these rails will get fixed at design time for various reasons (for example, the analogue supplies will usually depend on the analogue system design).

Again, is it really the case that this will happen in this system? Nothing is currently able to actually do that, and unless every consumer using a given supply is hooked into the regulator API things will go wrong when some of them start doing so.
