pretty sure that's the plan (some day bringing back the sharing) but since they just decided to drope the DRM system all together they have made a patch for that need to see if it's bug free and then find a new approach to allow the sharing if they are still doing it down the line....
the initial plan was to allow it for everybody even disc copies since it was merely a delivery support initially.... they probably didn't have real dissociation between DD and disc for the plan.... the patch is just lifting DRMs all together.... now they need to enable the sharing plan differently.... so first launch, patch, check if patch works as they planed, then study for sharing plan patch and solutions, then deploy patch....
that's how I see it anyway,
