Yeah with “lockable mode” I mean locking by default instead of requiring every program to specifically call for locking.
It would probably break lots of software, but only using such mode for the users home (or maybe even specific Downloads/documents/desktop/etc folders within the home directory) could reduce the impact.
[Edit] wait I think there is whole fs locking mode on mounting, with the “mand” option, going to test it.
