Short description of error

When using 'Bone Constraint: Action', after regenerating the controllers, the keyframes for the control bones are replaced with the ORG bones.

This prevents modifications because:

The original animation that used the control bones is permanently deleted.
The keyframes of control bones are replaced by ORG bones.
ORG bones cannot be manipulated, making it impossible to adjust the Action.

This behavior occurs when using the rig type "basic.super_copy".

Additionally, when using Relink Constraints to link the 'Bone Constraint: Action' to the CTRL bone, the action modifier does not work in any way because the keyframes are still replaced with ORG bones.

Exact steps for others to reproduce the error

Open a clean Blender file.

Create a new Armature.
Create the bone 'Action_Master'.
2.1 Select the Rig Type: basic.super_copy.
2.2 Leave the Control and Widget checkboxes selected.
Create the bone 'Simple_deformer'.
3.1 Select the Rig Type: basic.super_copy.
3.1.1 Leave the Control, Widget, Deform, and Relink Constraints checkboxes selected.
Create a new animation Action and set up the keyframes:
Keyframe 0 = all transformations reset.
Keyframe 9 = apply any modification to the bone.
Add 'Bone Constraint: Action' to the bone 'Simple_Deformer'.
5.1 Add 'CTRL: ' to the beginning of the constraint's name.
5.2 Configure the 'Bone Constraint: Action' to be activated when moving the 'Action_Master' bone.
Test if the 'Action_Master' is correctly moving the 'Simple_Deformer' according to the animation.
Generate Rig.
Test if the 'Action_Master' continues to move the 'Simple_Deformer' (This step does not work because, during generation, the animation keyframes were replaced with ORG.)

Suggested change in behavior:
Never replace the keyframes of control bones with ORG bones.

How to use the append file

Open
Movement bone Action_Master
See the bone Simple_Deformer moving
Regenerate the rig (Lose the animation)
Try to move the bone Action_Master again (in both armautres)
Nothings happens to Simple_Deformer bone (in both armatures)
