Review comment:
We use a similar approach in `PrimitiveType`. If we serialize `MetricsMode`
directly, it will be deserialized back on executors and we will have a problem
that `MetricsMode.None.get()` is never equal to our deserialized value even
though it was `none` before as we use `==` for equality checks.
