I have located and submitted a patch to correct a problem with grub2's
handling of a three-device (actually, anything more than two) btrfs
volume. Here is the bugzilla report:
https://bugzilla.redhat.com/show_bug.cgi?id=890955
And here is the patch:

Subject: [PATCH] support for multi-device btrfs volume
The current code produces error messages if passed a device
list with multiple devices for a btrfs volume. It worked OK
for single device btrfs volume.
This has been regression tested with root/boot on a regular
partition, single device VG logical volume,
and single device btrfs volume.
