Since v5 relies on node >= 18, this is now possible (since v16, v14.18.0 [^1][^2]). It's functionally irrelevant: 1. It's not required for CJS nor ESM (with a few exceptions [^3]) 2. It has no performance promises However, there are upsides to this approach: 1. It brings clear boundaries to what's a built-in and what's an external dependency 2. It reduces the risk of importing unwanted deps where a built-in is expected 3. It's slightly more interoperable with other JS runtimes that provide node compatibility[^4], albeit only during development. Once imported from npm, built-ins are assumed.
