Can we get some tests for these or some e2e tests? Orders are kind of tricky where most of these details will typically be on each shipment and not on the parent order (addresses aside). I'd like to avoid adding params that aren't valid at the parent level by testing first.

In draft while discussed internally.

We have confirmed internally that these parameters are accepted in certain multi-parcel scenarios. It's not guaranteed that they will always be respected versus ignored, but it's important that we make them available for end-users to use as needed.

I feel better with just exposing return/buyer addresses
