This is disheartening to hear. We recently (<3 months ago), introduced Btrfs into part of our fleet. This probably made us one of the larger Btrfs users. If Btrfs falls out of general favour, I'm afraid it may impede our ability to keep using it.
Given our use-case, multi-tenant containers, there weren't many choices which had sane snapshotting support, as well as quotas and some level of subtrees. ZFS on Linux has its own share of issues. I won't say that Btrfs was without issues -- there is still a lot of performance work that needs to be done, especially in a multi-tenant workload, but it looked like there were solutions available.
XFS is an excellent filesystem, and it may work well for our usecase in the near future. It's exciting to see new XFS features landing, like reflinks, and collapsing ranges. Hopefully, folks like Redhat continue trying to bring XFS to the future.
