Sway's necessary privileges can now be obtained through seatd as well as the
incumbent polkit package. As such, polkit has been relegated to an optional
dependency.

Note that using seatd instead of polkit means that a user must be a part of the
"seat" group: Otherwise, the user will not be able to achieve the appropriate
privileged actions.

For more information, refer to the Sway wiki page.
