We could prefix series of fields with the value they are logging. So for instance, the 4 completion latency fields would include a clat prefix first: clat[%lu;%lu;%f;%f],foo[%lu;%lu],etc Would that not be more resilient to future changes? New fields would not bother you, and reordering should also be fine.
