It's hard to be opposed to that. Having seen a teenage girl give her testimony via a recording so that she didn't have to be present in the courtroom, I know the process works and takes a bit of pressure off the victim.
With respect to adult women, they can of course experience a significant amount of stress and they do have the option of obtaining authorization to record their testimony. Some women want to be there in person to face their attacker, but others find it too difficult. That provision can definitely be helpful to victims.
