A codepath which is perfectly fine in testing/staging could kneel over immediately against a production workload,

A code path that works well in one test can easily buckle under the pressure of a production workload. Stress testing is hard.

We're not talking about a codepath that's working in testing and falling over in production. The person I responded to was suggesting a codepath that's not even tested in testing, and I was hoping to understand why begin would be such a codepath.
