System Information
Operating system: Linux-5.3.0-7629-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce RTX 2080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.44

Blender Version
Broken: version: 2.90.0 Alpha, branch: HEAD, commit date: 2020-07-02 12:26, hash: f58f09c9a9

Short description of error
For example, the built-in Bone Selection Sets addon stores some things as python properties:

bpy.types.Object.selection_sets = CollectionProperty(
        type=SelectionSet, ...)
bpy.types.Object.active_selection_set = IntProperty(...)

When linking an armature and making a library override of it, these properties can't be edited and can't be overridden. I tried adding options={'LIBRARY_EDITABLE'} to these property definitions, but it didn't seem to make a difference. I also tried drawing them on the UI directly (as sliders) and storing them in bpy.types.Armature instead of bpy.types.Object, but to no avail.

Exact steps for others to reproduce the error

Enable Bone Selection Sets addon
armature_to_override.blend
Link the collection in above file to a new file
Make Library Override->Armature
See how Selection Sets are grayed out - you can't change the active selection set, and you can't rename any of them.

CC @mont29 Is this supposed to be supported? I couldn't find a todo task, sorry if I'm being blind or dumb.

Well, the tooltip says:

Disabled: Can't edit this property from an override data-block

I'm not familiar with this area, but from what I see, it doesn't look like a bug.
Otherwise the limitation would not be described in the blender itself.
Did I get something wrong?

I suggest using other channels for questions like that: https://wiki.blender.org/wiki/Communication/Contact#User_Feedback_and_Requests

I poked Bastien IRL and from what I understood/from what I remember, he said it's supposed to be working, so I think it might be a bug. But it's possible he misunderstood what I was asking about. poke poke @mont29

If this part of library overrides is still work in progress(an so this is not a bug) then ofc feel free to close this. But, this does mean that we had to go back to using proxies still, which makes us all sad! D:

This is more a TODO than really a bug, since it was never implemented. But thanks for the report, easier to keep track of this and not forget about it then. ;)

See D8249: Refactor override code to properly deal with runtime rna properties too. and D8250: Expose override flags to python RNA properties definition.
