Not just deferred message propagation, but also a way to setup medium to high powered rebroadcasting stations. For political unrest scenarios, you don't always need 2-way communication, but you do need to distribute critical info. A listen-only mode makes it very difficult to track individual users (no RF transmissions), and would cover a large percentage of a critical use case.

All of this is solved with the store-and-forward model that you highlight.

A Lora dongle seems to be better than BT, though potentially incriminating.
