It is an even bigger deal for the digital world, actually. At the moment, you are pretty much required to add a capacitor right at every power pin to (among other things) prevent high-frequency radiation from escaping. It's not uncommon for moderately complex chips to need half a dozen capacitors. Capacitor placement has a huge impact on board design. Not having to worry about them anymore would save a tremendous amount of engineering effort.
