I think it's fair to say that `interface{}` is somewhat special in practice
because it acts as an escape hatch from the type system when necessary. No
other interface is capable of being satisfied by values of all types. I
assume that the `error` interface is pre-declared because it's a very
common interface used across almost all Go code. If `interface{}` is to
become even more common than it is thanks to generics, I think it could be
reasonable to follow the same thinking.
