-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 XEP-0256 talks about including last activity in auto-away notifications, which means "I'm away at this resource and I was last active at time T."
Another possible use case is including last activity in initial presence, which would mean "I'm newly online and I was last online from this resource at time T." The attraction here is that pubsub and PEP nodes to which you subscribe might be able to optimize item delivery (e.g., by sending you only the items that were published after you went offline the last time, give or take a few minutes). The same might be true of MUC room history (I am growing tired of receiving messages from yesterday when I join a quiet room).
