I guess they could be added already to v2.2, but enabled only by a new setting because it requires file format changes that old Dovecots can't then read. I could probably patch v2.1 also so it is able to at least read the new format without failing. For v2.3 this new format could then be made the default.

What would these solve? Pointing out errors in dovecot, operating

Modern file/storage systems checksum the data all the way to the platters.
