I think the point of OP's comment is that while you're not paying code tax for to parse/aggro the data as it's all in one place you're paying code tax for actually generating the event with everything in it.
Sure you still need to code but instead of concrete metrics one by one, you instrument the context and the state. The opentelemetry trace API can save you a lot of work. But I agree there is still potential to improve the auto instrument.
