On iOS, Signal has implemented a data transfer from one device to another directly. It's of no use if one loses one's device or just hands over the old device to someone else before completing the setup of the new one (people are accustomed to setup a new device from backups in the cloud, which Signal won't support).

"Won't support" is wrong, this is explicitly on the roadmap, they've stated that multiple times. "Doesn't currently support" would be more accurate. For the technical aspects, secure cloud backups are going to be made possible with https://signal.org/blog/secure-value-recovery/.
