Correct, and outbox will evolve..

yup
it's really "smarter relay selection" where the outbox model is one way of doing it
Exactly.
Even negentropy is part of that category indirectly, given it’s a form of note propagation like blastr — set reconciliation is just more advanced since it doesn’t redundantly propagate notes relays are already storing.
If you chose a Strfry relay in your relay list, it’s basically a mini-blastr most of the time!
