Hang on, does that also mean commands like 

 btrfs balance start -f -sconvert=raid1 -mconvert=raid1 -dconvert=raid1 /

Would only make that subvolume raid 1? Or would it make the whole "filesystem"
raid 1.


Regardless, the administration point of a filesystems being dependent on
subvolume paths and the subvolume properties is really problematic.
