I'm no big company, but I've been using btrfs on my Raspberry Pi file server and its disk has been sitting there spinning for something like 8 years with no issues yet. I keep hearing that "btrfs isn't production-ready" but I wouldn't know it from experience.

Perhaps you never lost data from it years after it was billed as ready for use, but many people did. I've never lost data on Reiser3 or Reiser4. I've not used bcachefs or f2fs much yet, but I've never lost data on those either.
