Same reason newer filesystems like BTRFS use checkusms (BTRFS uses

True, but presumably neither does it have anything it can do to
rectify the situation if it finds a problem, and the client will
have to keep its own secure hash of its file anyway. (Unless I suppose
the server actually can request a new copy from the client or another
server if it finds a corrupt file?)
Yes. The storage servers are monitored for integrity. They can request
a new copy, though frequent corruption results in the server being
marked as unreliable.
