Especially if you use LVM and leave free space in the VG.  If you're a
slice-and-dicer and you fully allocate and/or use fixed partitions, then
using XFS you may come to regret, say, a 10 gig /var and a multi-hundred
gig root, but if you left root closer to the size it needed to be, you
just lvextend and xfs_growfs as needed.
