Description

Landing page = org. is pretty cool, thank you very much for it - there is only one thing that is not so nice. We have some organistions for internal use only - there will never be public repos in it. So these organisations shoud have a private/non-public flag or should only been shown when at least one repository in it could be watched with the viewers rights.

Sample: https://git.lxqt.org - administration, container and instances will never contain any public stuff.

This is similar (not the same though) to the following feature request: #2908

This comment is just so that the two tickets are linked.
