If I remember correctly at a Vault Conference few years ago Dave Chinner say that xFS codebase while actively maintained should be considered legacy since it's not really possible evolve it anymore and the better way to go is a complete re-design so a new filesystem, a thing that will not happen in xFS upstream... I do not find any transcript now, but looking for it somewhere in the web surely exists :-) So yes, it's rock solid and battle tested, certainly a safe choice respect of btrfs (buggy and not really good in production despite many do not care) or bcachefs (solid, stable, but essentially feature-less in today's implementation) but nothing more... RH and Oracle seems to push it a bit inconstantly but I still have to see any real plan...
