Whatsapp problem isn't in the algorithm, but their identity resolution (hence their roundabout way of doing their web client: https://github.com/sigalor/whatsapp-web-reveng) iMessage approach is to treat every conversation as a group chat between all the recipient devices and all of yours. There's another risk here, that Apple doesn't let the end user verify the list of devices the chat is encrypted for. Which is to say, a perfect E2E experience isn't trivial to design, but you don't have to drop the ball completely.

Hi, that's definitely not a noob question. I'm already having plans on investigating this, but this topic is even more difficult than WhatsApp Web itself (see https://github.com/sigalor/whatsapp-web-reveng/issues/10#iss... ). Thus, at this time, I am not able to give you a definite answer, though, to put it informally, "it looks good" (at least on the surface).
