Feedback Why does AnimationUtility.GetEditorCurve Return the most unoptimized version of a curve?

I'm using the this call: https://docs.unity3d.com/ScriptReference/AnimationUtility.GetEditorCurve.html
I use it for some custom animation system for myself. The source curves in the AnimationClip is perfectly simple and just a normal 2-6 keypoints curve generally. When I export it to a standalone AnimationCurve it becomes a mess.

Becomes this:


Why? The curve data is right there in the editor in the optimized version! Is there a way to get the ACTUAL curve you look at in the animation editor?

Edit: I realized one of them are the quaternion version of the same rotation animation. So is that the problem? In that case, can I get the euler version or a better quaternion version?
