> The current implementation of multi actions uses repeated "NameBytesPair"s for the contents
of multi actions. Instead, we should introduce a union type protobuf for the valid actions.
This makes the RPCs smaller since they don't need to carry class names, and makes deserialization
faster since it can avoid some copying and reflection.
