The idea that an application can or should care that the IP address of a

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.
