Thanks for the clarifications. It seems I was mistaken about Object.setPrototypeOf.
1. I didn't realize in this context[1] "Object" included Functions, Errors, etc... 2. Reinforced by Object.create being object specific. Given this, it's understandable why you thought I was bizarrely expo on Function.create. At any rate, we're in complete agreement here.
