XFS isn't everything. The checker for XFS requires something like 1GB of RAM for each 1TB of disk space. This doesn't sound bad until you want to install a machine with 96TB of disk and 64GB of RAM. You then find out that the ext4 user space tools can't init a disk that big and XFS can't check a disk that big. :(

Using xfs_repair -n is a workaround, but still (IMHO) a hack.

Or you could use an old Unix trick of the trade: use four or five smaller filesystems rather than one huge one and not put yourself completely in the crapper should one of them get corrupted. (I'd have been in much worse trouble if I hadn't split the frequently-written-to /var off from the rest, for instance.)
