Cause itâs overkill.

There is no hardware/abstract device connection between an overlay and a device as whatâs being used right now in driver core.

kobjs are enough to present them in the filesystem hierarchy.

They have to be in sysfs so that people can have information about the overlays applied in the system, i.e. where their targets are and whether removal is possible. Thatâs whatâs possible for now; in the future we might present the full contents of the overlay there, and what changes to the live tree were made.
