200 people are the primary owner of at least one file in frappe/erpnext, and Ankush Menat owns the most: 974 files, or 27% of the codebase. The truck factor is 6: that is how few people would have to leave before the majority of owned files lose their owner. 1,917 files have exactly one contributor, and 2 modules are dominated by a single person.
