There still are. As someone who has done both production and homelab deployments: unless you are specifically just looking for experience with it and just setting up a demo - don't bother.
When it works, it works great - when it goes wrong it's a huge headache.
Edit: As just an edit, if distributed storage is just something you are interested in there are much better options for a homelab setup:
- seaweedfs has been rock solid for me for years in both small and huge scales. we actually moved our production ceph setup to this.
- longhorn was solid for me when i was in the k8s world
- glusterfs is still fine as long as you know what you are going into.
