> Came across a use case where it would be great to be able to have support for deserializing
protobufs using an ExtensionRegistry for some custom message extensions. ExtensionRegistry
isn't serializable and there isn't a good way to serialize it using the current protobuf libraries,
so I also created a Serializable extension of Guava's Supplier interface to handle cases where
we need to specify how to construct an object for use in a DoFn as an external argument, which
seemed fairly useful.
