well, /boot support is the least of the problems. grub doesn't support
ext4 on /boot yet either, and grub does the wrong thing for xfs so
that's excluded too. A separate /boot is pretty commonplace.
Aside from mkfs, Anaconda also needs to be able to detect fs types - it
uses blkid for that, but there is not yet a stable btrfs disk format for
blkid to recognize, so blkid can't get updated yet.
So it's all still a ways off.
But if you want to play w/ btrfs, you can almost certainly build the
kernel module against the kernel-devel package and have something usable.
(And since rawhide's btrfs-progs is already stale, I guess you can just
build that from source, too) :)
