The "WhatsApp Business API" client also offers the ability to backup/restore the Signal cryptographic identity, because it would be a bad experience for end-users to see identity change notifications from businesses every time their IT person decides to fiddle with their servers.
It would be nice if this could be done on smartphone clients, but that pretty much requires leveraging some sort of "trusted key store" external to the app. (Which I'll admit may exist on some platforms, to varying levels of trust. How feasible and acceptable it is for this use case, I honestly do not know.)
