Error is far from empty; it appears that way, but it contains default implementations to make bridging to and from Cocoa NSError objects much more convenient, especially since SE-0112. Plus, it’s a protocol rather than a base class, so conforming it doesn’t really constrain your design in any way.

-1 on removing Error.
