Yes, we considered it with varying depth on multiple occasions and never found a satisfactory solution. Since graph stages are free to transform not only individual elements but also the stream structure the conclusion was that the metadata cannot be hidden from the graph stage code, it must be explicitly foreseen. This will then also need to be reflected in the types. One idea was to create a DSL on top that offers certain well behaved combinators for tagged elements, but as far as I know this has not been implemented yet.
