IIRC, some time ago it was stated that the plan was to move to BTRFS. It is not clear to me that everyone is onboard with that decision. Or, perhaps that decision is being reconsidered.

Well that's exactly what it is, go away I'm busy with other stuff :). The fact is I'm the only one who can drive btrfs as the default filesystem feature in Fedora, and since I've left Red Hat that has become much less of an priority for me. But my "other stuff" is still mostly related to btrfs, so its not like this has just been abandoned, the focus has just shifted and I no longer feel like we need to be using btrfs as the default fs in Fedora to have a successful project, so it got moved down the priority list. It will happen, and when it happens it will be relatively painless because Suse will have worked out a lot of the distro esque kinks and us at Facebook will have worked out a lot of the at scale kinks. Thanks,
Josef
