Since 5.3 we no longer can configure spaces on the user group level, only on system level. Spaces are hidden when no assets can be found based on the users permission.
We need to be able to configure spaces on user group level as we want to present different sets of spaces to different user groups, independent of the fact that a user could find assets in a space or not. Hiding spaces when there is nothing to show would give support questions "where did my spaces go". Better would be to show the number of records in the space on the Spaces landing page.
