On the contrary, the idea that an application must not care that the IP address of a packet is consistent from source to destination is plain bonkers. Even assuming the existence of a higher level identifier and a secure, fast, scalable, reliable way of finding routes to that identifier, there will still be some need to talk to a host or an interface. And nobody has demonstrated an application-independent mapping service that is anywhere nearly up to that task. Until somebody does, statements about what the architecture "should" do, or what applications "should not" do with addresses, are at best wishful thinking, and at worst delusion. And the more often someone makes such a statement without qualification, the more it looks like the latter.
