Seems plausible if older kernels don't understand skinny-metadata, that GRUB2 won't either. So I just tested it with grub2-2.02-0.8.fc21 and it works. I'm surprised, actually. The way I did this was creating a whole new fs with -Oskinny-metadata and using btrfs send receive to copy an existing system over. Kernel reports at boot time that the volume uses skinny extents.
