It doesn't feel good to be locked to the horizon for small accelerations in space, even when they exceed 0.05g. Perhaps this system should be limited to centrifuges and cases where the majority of the subjective acceleration is from gravity (e.g. cruising flight in a plane).

Possibly related: the camera orientation changed here when docking, it may have been from acceleration: https://youtu.be/WC1I0-plCVg?t=30
