What if you run node with --no-experimental-fetch? Then globalThis.Headers will be undefined. Thus breaking the code.

As a side note, but not majorly important: isPrototypeOf is also resilient against Symbol.hasInstance shenanigans. The real benefit is needing less imports to perform brand checks now that it is unified.
