From my investigation currently Flink use {{SlotSharingManager}} and {{SlotSharingGroupId}} for achieving slot sharing. And thus {{SlotSharingGroupAssignment}} {{SlotSharingGroup}} and {{SharedSlot}} are all legacy concept.
Notice that the ongoing scheduler re-design touches frequently tests based on legacy slot/instance logic or even uses it for testing. I'd like to nudge this process for totally remove legacy code from our code base.
Also I attach a patch on FLINK-12179 that remove {{Instance}}. With current contribution workflow your shepherds are significant :- )
