Is instanceable robot no longer a need?

Question

I am noticing that in the lab_assets folder
some of the robot usd_path no longer points to the instanceable usd, which was proposed to speed up the loading

I wonder using is using instanceable still relevant or not necessary anymore?

ANYMAL_C_CFG = ArticulationCfg(
    spawn=sim_utils.UsdFileCfg(
        usd_path=f"{ISAACLAB_NUCLEUS_DIR}/Robots/ANYbotics/ANYmal-C/anymal_c.usd",    
        # usd_path=f"{ISAAC_NUCLEUS_DIR}/Robots/ANYbotics/anymal_instanceable.usd",      <--- instanceable is commented out
        activate_contact_sensors=True,
        rigid_props=sim_utils.RigidBodyPropertiesCfg(
            disable_gravity=False,
            retain_accelerations=False,
            linear_damping=0.0,
            angular_damping=0.0,
            max_linear_velocity=1000.0,
            max_angular_velocity=1000.0,
            max_depenetration_velocity=1.0,
        ),
        articulation_props=sim_utils.ArticulationRootPropertiesCfg(
            enabled_self_collisions=True, solver_position_iteration_count=4, solver_velocity_iteration_count=0
        ),
        # collision_props=sim_utils.CollisionPropertiesCfg(contact_offset=0.02, rest_offset=0.0),
    ),

I am also noticing bugs related to using instanceable such as:
when reference path is "./origin.usd", isaac lab is not able to resolve referencing when program is launched from standalone, but such reference is resolve when directly import instanceable from gui.
