Most (if not all) of those APIs are designed to be used with or without
systemd as initmanager, that is why there are seperate shared libraries. I
need to double check, but polkit might be the only exception to that in that
it needs to have systemd actuall running. But multi-seat is broken anyway
currently, so not much difference for the end user either way :)
