We could really use something like Partnered collaborations for ArcGIS Enterprise. It could be ArcGIS Enterprise to ArcGIS Enterprise or ArcGIS Enterprise to an ArcGIS Online organization. This would save a lot of time sharing data between organizations by being able to add content to a group and add members from other organizations to that group.
The current distributed collaboration share by reference has only ever worked for us when content was shared with everyone. If we add something to that collaboration that is not shared with everyone anyone in the other organization gets a prompt to sign into our ArcGIS Enterprise deployment.
