Part of the problem is replicating fs bugs that take months/years to occur is nearly impossible... people still sell USB to SAS/SATA adapters that cause large file corruption in hardware too.

ZFS does have bit-rot checksum detection/repair, but the encrypted file feature was a bit of a YOLO feature for awhile. Not sure where it is at these days, as ddr5 ram prices skew away most of ZFS best key features. =3
