FWIW, I still think it's a mistake to accumulate all these bespoke
tools. We should go towards having one tool that can verify checksums,
validate backup manifests etc. Partially because it's more discoverable,
but also because it allows to verify multiple such properties in a
single pass, rather than reading the huge base backup twice.
