Mail goes from one sender to one or more recipients. You can think of the 
outgoing mail route as a tree, branching at certain points where mail is 
relayed or forwarded through different hosts. What I would intend to deliver 
to each recipient is information about the particular root-to-leaf path which 
reached them, not that of any other recipient. This means that each recipient 
gets a different bundle of delivery metadata, whereas they all get the same 
message metadata. That's one of the compelling reasons for keeping the two 
bundles separate in the first place: one is static, the other dynamic.
