Rancher 2.6 Gluster Volume Unsupported

I just updated one of my cluster to Rancher 2.6. I noticed that Persistent Volumes with Gluster Volume type are unsupported. Everything seems to be working fine though. What that “unsuported” claim mean? Should I be concerned? Or do I need to change some settings? I have feature flag for unsuported-storage-drivers set to Disabled now.

Unsupported means literally what it says here; we provide commercial support for a limited set of drivers and Gluster is not one of them. It can work fine if enabled and used appropriately.
