> cross-device message history sharing by default, which is not possible in case of e2e, without key transferring
iMessage does that† (is that what you mean by "key transferring"?). I wish it could display the device key fingerprints somewhere, allow for key pinning, as well as offline key exchange between parties though††.
† in fact history is not centrally shared: messages are encrypted and published once per receiving device by the sender.
†† And be cross-platform. But the optimist in me says it's to control the security experience while the cynical in me says it's about network effects (although mitigated by SMS integration) for commercial reasons.
