The HEVC decoder will start setting stereoscopic view position (left or right) based on 3D Reference Displays Info SEI message in future commits. This information should be merged with container-derived stereo3D side data.
After this set, a re-encode with the CLI will have information at the container level that may not be correct, like type and view.
For mv-hevc it probably makes no difference currently, as type unspec and frame sequence are not supported values in any container, and view left/right is only supported in mov eyes box, which we currently don't write, but it nonetheless needs to be handled in some form, like by propagating global side data through the filterchain as you suggested.
