I have never worked on a properly hardened desktop app, so I don’t have much of a perspective on that, and can definitely see that it might not be worthwhile for the signal team.

I would appreciate some level of encryption, thinking that it might help with less targeted attacks. I’d also appreciate a Web client, like Threema’s with none permanent sessions. But all that’s, as you’d say in German, “Meckern auf hohem Niveau”, especially since I’m not currently contributing to Signal.
