Support for exporting tracing data

Could Cloudflare export opentracing data about requests flowing through our account?

e.g. It would be great to be able to go to my account page, enter our datadog api key, and have trace data start being sent. Requests from cloudflare to the origin would include the relevant opentracing headers, so we’d see the complete path of the request.

Can appreciate that there may be lots of commercially sensitive data inside Cloudflare here, so I’m not anticipating seeing all the innards. I imagine seeing at least two spans - One showing the time of “request entered cloudflare’s network → response sent to client”, and another “request sent to origin → response received from origin”.
