Description of problem: The part and logvol directives (in a kickstart) support the --fsoptions argument to provide additional options used in fstab. This argument is missing for th ebtrfs directive, thus it is not possible to define additional fsoptions for fstab for btrfs partitions.

We do propagate options supplied for btrfs member partitions to the volume. You could see if that works for you.
That works for me!
