Don't worry, they are working fine.

Except for "Device lock faith text" (already discussed), as an emergency call feature seems to be available in the regular (unpatched) device-unlock-screen since SFOS 3.0.3 (I have not tried it yet). Edit (2019-05-15): This emergency call feature was long available, it is just the layout of the unlock-screen in landscape orientation, which was altered (and confused me).
Unfortunately Jolla did not implement the option to display ICE ("in case of emergency" / "medical card") information, which "Device lock faith text" nicely provided, so this functionality is currently lost (Edit: plus the "faith text" proper and the option for a preset number to call).
