Ref T13411. These three applications render an "Editable By: <policy>" field in their descriptions.
The pages that these appear on all have "Edit <thing>" actions which either tell you the policy or allow you to discover the policy, and this field is unusual (the vast majority of objects don't have it). I think it largely got copy/pasted or used as space-filler and doesn't offer much of value.
Remove it to simplify/standardize these pages and make changes to how this field works simpler to implement.
