Greptile Summary

Removes unused physics and renderer capability methods and deletes empty video-recording packages.

• Removes capability APIs and their backend overrides from IsaacLab, Newton, OV, and PhysX.
• Removes empty Newton and PhysX video-recording package initializers.
• Adds major-version changelog fragments for each affected package.

Confidence Score: 5/5

The PR appears safe to merge because the removed methods and packages have no remaining repository callers, imports, or registration dependencies.

The removals are applied consistently across base classes and backend overrides, while targeted checks found no reachable in-repository use of the deleted APIs or package paths.

Important Files Changed

Filename	Overview
source/isaaclab/isaaclab/physics/physics_manager.py	Removes the unused implicit-damping capability method; no repository callers remain.
source/isaaclab/isaaclab/renderers/base_renderer.py	Removes the unused temporal-camera-data capability method, with corresponding backend overrides removed consistently.
source/isaaclab_newton/isaaclab_newton/video_recording/init.py	Deletes an empty, unreferenced package initializer with no registration side effects.
source/isaaclab_physx/isaaclab_physx/video_recording/init.py	Deletes an empty, unreferenced package initializer after its prior recording hook dependency had already been removed.

Isaac Lab Review Bot

This PR removes two public capability classmethods and their backend overrides, plus two empty video-recording packages. The capability methods are deleted without the prior deprecation required by repository policy.

• Design and architecture: Removing the capability-probe layer is internally consistent because the base methods and all shown backend overrides are removed together. However, architectural cleanup does not bypass the compatibility policy for public base-class extension points.
• API: PhysicsManager.provides_implicit_damping and BaseRenderer.provides_temporal_camera_data are documented public classmethods that external backends may call or override. They must be deprecated for a release before removal; the changelog’s major bump and migration note do not replace that deprecation period.
• Implementation: The method deletions are localized and corresponding in-tree overrides are removed. Restore the base-class methods with deprecation warnings, classify the current changelog entry as Deprecated, and defer deletion until a later release.

🟡 Warning · Api — Public capability methods removed without prior deprecation

PhysicsManager.provides_implicit_damping and BaseRenderer.provides_temporal_camera_data are public, documented classmethods on base classes that out-of-tree physics backends and renderers can override or call; both are deleted outright here. Repository guidelines require deprecating public API symbols in a prior release before removal. Keep the base-class implementations with a deprecation warning and file this fragment under Deprecated, then delete them in a later release.
