I'm no cryptographer but I can see that messages are signed before they are encrypted, for no obvious reason. That's failing the cryptographic doom principle (https://moxie.org/2011/12/13/the-cryptographic-doom-principle.html https://moxie.org/2011/12/13/the-cryptographic-doom-principl...) and so should be taken with care. OTOH the drop of Signal Protocol features makes sense in their appreciation of real world: as soon as an attacker has full control of the device all the protections fail. This is probably the number one source of working attack anyway
