KVM (RHV, OLVM, Proxmox VE) • BTRFS support dropped in 12.3.1.1139?

Hello,

Just noticed yesterday, upgrading my home lab to 12.3.1.1139 than support for BTRFS storage seems to have been dropped.
Doc (now?) says it's unsupported and backup and restore no longer works, but it has been working since the first beta release of Veeam backup for Proxmox.
Now I'm reverting to 12.3.0.310 for this.
Does someone know when BTRFS will be supported again? I don't get why Veeam implements breaking changes like this in a security patch.

Have a good day,
