Due to the way PropertyWrappers are implemented and some current Swift constraints, the currently available wrappers don't support Optionals. Simply creating an optional version will fail with a missing key when decoding, but there is a workaround pointed out here.
API is TBD, but the workaround should be used for now and deprecated when new features are available.
