A CRC, no, absolutely not. But this is exactly what PAR2 recovery records do, they do it well, and they (or their equivalents) need to be easier to enable in more places.
Setting up a replication and durability scheme is a major pain in the ass. Passing the `--add-recovery-record` switch on the command line is very, very easy, and it is good enough for many cases where "best effort" protection against corruption is all that is needed.
