Maybe we are focusing on different problems, but to me the main
one is a spec/expectations clash: For user-friendliness, we want
relevant properties of sources to be preserved in destinations.
But for generality, we want anything to be put into anything.
This shows up mainly in orderedness, but you can imagine users
"expecting" any other property as well (like sortedness wrt a
comparator). I think this is a no-win situation.
