Would something like this help with #10 ?

Closing, since we changed the record format:

{
    "time": "xyz",   // from handler
    "request": {
        "time": "xyz", // request time, from middleware
        "path": "/hello/world",
        ...
    },
    "response": {
        "time": "xyz", // response time, from middleware
        "duration": "10ms",
        "status": 200,
        ...
    },
    ...
}
