Answer 1

In most cases, it is not useful. Static fields are indeed not serialized by the default serializer.

However, static transient fields can be detected via reflection. If someone writes its own serializer and he wants to also serialize static fields, then he might take the transient keyword in consideration and skip the serialization of that particular field.
