Short description of error
The datablock-level property "use_onion_skinning" on the Grease Pencil datablock doesn't seem to do anything. Toggling the property with Python doesn't affect the visibility of onion skinning.
Working as expected, this property will be useful when drawing among multiple Grease Pencil objects.

Exact steps for others to reproduce the error
Open attached blend, toggle use_onion_skinning in the Python console: bpy.context.object.data.use_onion_skinning = False onion_bug.blend

This prop is not used and would be removed. Now the onion skin is controled in Overlay with the prop use_gpencil_onion_skinand is not by datablock. You could disable the onion using the prop at layer level for each layer of the datablock.

@PratikPB2123 Not sure if we must set the task as Archived or as Known Issue.

I see, but IMO it'd be useful to retain: I often find myself drawing among multiple Grease Pencil objects, each with many layers, and with multiple viewports open on one workspace, which I expect will be a common situation in storyboarding and LineArt workflows. In this kind of case it would be convenient to be able to toggle onion skinning on each object as a whole across all viewports, rather than having to either turn onion skinning off globally (and only per-viewport) with the overlay prop or have to chase down each individual layer. Was glad to find this property existed, but discovered that it wasn't working after writing an addon exposing it to the UI in the Dopesheet and Property Editor.

I will mark this as known issue since the property existed but not working as expected
