Many Esri platforms are set to retire in 2025/26; I think it would be very convenient if these items were highlighted some way, or starred with a 'Deprecated Platform' note in ArcGIS Online. This way users can easily view which items they may need to recreate before they are unavailable. I think this would be simple to implement but very handy and insightful for users. Although an admin can try to put together a list and notify users, there might be items inadvertently missed with filtering or running identification scripts.
I appreciate any consideration. Thank you!
