SystemD wrecking artist Lennart Poettering has proposed a substantial reworking of the way Linux handles users which would break many of the ways Linux is actually used under the pretext that the changes would make him feel more comfortable leaving his laptop in a suspended power state (archived).
Most notably Lennart's new user and authentication model would require users to already be logged into a system locally in order to access a shell over ssh. Under the new Lennart login model, if the user isn't locally logged in the authorized_keys file for the user will be encrypted and inaccessible to the system preventing ssh authentication. Typical of Poettering efforts this latest proposal breaks numerous things that work to implement hypothetical mitigations of purely constructed dilemmas, like Poettering's supposed aversion to turning his laptop off.
