The old pose library should be removed from the UI in Blender 3.2, as discussed in the [2021-11-25 Animation & Rigging module meeting](https://devtalk.blender.org/t/2021-11-25-animation-rigging-module-meeting/21536).
- [x] Removal of UI panel in the Armature Properties panel.
- [x] Removal of the operators from the Pose menu in the 3D Viewport.
- [x] Make a concrete list of Python functionality/APIs to deprecate.
- UI templates:
- `template_ID(ob, "pose_library" ...)`
- `template_list("UI_UL_list", "pose_markers", ...)`
- Operators:
- `poselib.action_sanitize`
- `poselib.apply_pose`
- `poselib.browse_interactive`
- `poselib.new`
- `poselib.pose_add`
- `poselib.pose_move`
- `poselib.pose_remove`
