This is the only way to build these systems. If you are building a new house, wire everything to a central location. This way, any necessary upgrades can all be a matter of swapping out hardware. Even with the switching, if Lutron goes out of style, atleast all of the switch-legs are run to a central location. The entire system could be replaced (and the devices). It would not be cheap, but at least it's possible. Replacing devices in the wall isn't the worst thing in the world.
