Resolution Note:
While `Keyframe.tangentMode` was accessible at runtime, changing it didn't do anything. It's used specifically by the Animation Window to adjust the tangent automatically when changing keyframe. Hence the reason why we moved the functionality in UnityEditor.
To change the tangent at runtime, you'll need to change `Keyframe.inTangent` and `Keyframe.outTangent` manually.
