I am wondering how things like OpenTracing-esque spans and sub-spans fit into the format Stripe describes. Are they just logged as `subspan1`, `subspan2`, `subspan3` in the log format? It seems like that works, but I'm also unclear if maybe each sub-span is better off as its own log line? But that carries its own problems.
