I mean, it'll tell you that your only copy of a file got corrupted, but it'll still be corrupted...

Never underestimate the value of a reason to play Quake 2.
At the very least, a checksum failure might tell them (or the tech they're consulting) that they have a data problem, rather than, say, an application compatibility problem.
Some filesystems can be configured to keep two or more copies of certain filesystem/directory/etc. contents. Two copies is enough information to do something useful.
How big an issue this is in practice I don't know.
