My first thought is that it seems sensible if it's used as a regulated
supply in a context where just a plain regulator might be used like
MMC/SDIO type things.  If it's only setting logic levels for I/O pins
but isn't something that's being dynamically managed or really visible
to software (it's just a board design thing) then it might not be worth
it but if it might be controlled by changing an external regulator then
using the same API seems like it might be sensible.
