Hello,

the node: protocol is not yet supported by all the LTS version of Node.js meaning that people needed a specific version of Node to have it working.

For now, I don't think this is available enough to have it by default in the examples.

Is it okay if I leave the pr open until that happens?

Didn't know about the node: protocol, thanks for letting us know about it! It's definitely OK to keep the PR open until it's extended enough so it's safe to make it the default in the examples 👍
