With the migration to wlr_scene, some objects (desktop, output etc) will no longer have any reason to care about individual shells and similar; handling each one on its own would introduce code that is, from their perspective, over-complicated. Strata (sg. stratum; this name was chosen to avoid confusion with the over-used 'layer') represent logical layers of surfaces on the desktop, such as every layer shell layer, one for xdg shell, another for popups.
