It currently has two valid settings. The protobuf in the name refers to the new client protocol (which we're calling the protobuf protocol). I don't think we're quite ready to take the feature flag out yet, but we should consider it as this feature nears alpha. Or moving the feature flag to a better config mechanism (DistributionConfig), so that this property and that one are in approximately the same place.
