Atlassian has done something unthinkable. They have rebranded a bug as a feature and closed it with resolution = "Won't fix"! Confluence had (or still has, in old navigation) a simple yet immensely useful feature where a user could setup an overview page of a space as their home page. However, this feature stopped working in the "new experience". A bug was duly filed. And, lo and behold, it has been declared a feature.
