@ben @crepererum @besendorf even if PFS would become part of delta chat e2ee (it is for transport encryption already) it's just one concern out of many and the "but email!" folks would pull out a new obstacle likely :) Besides,
PFS has serious implementation/complexity and multi-device usability repercussions so for now it's not a focus. Meanwhile https://securejoin.readthedocs.io allows delta users to have guaranteed e2ee even if the servers and intermediate nodes are compromised so there is that.
@delta @crepererum @besendorf PFS is overrated
