This is correct. It's a seemingly simple desire -- "always capture whenever there's a request with an error!" -- but the overhead needed to set that up gets complex. And then you start heading down the path of "well THESE business conditions are more important than THOSE business conditions!" and before you know it, you've got a nice little tower of sampling cards assembled. It's still worth it, just a hefty tax at times, and often the right solution is to just pay for more compute and data so that your engineers are spending less time on these meta-level concerns.
