IMO. Preparatory bits are in patches: btrfs-progs: mkfs: add names of matching sysfs feature names btrfs-progs: mkfs: enhance feature table btrfs-progs: mkfs: extend mkfs features with compat, safe and default versions the core work is not yet done. The original usecase has been extended to allow for selecting features that are compatible, ie. can be mounted, safe, ie. are ok wrt The Status page, and default, ie. automatically selected by mkfs. Additionally to that, a system-wide preset from a config file in /etc.
