Thanks, but given there were equally as many issues with using a fixed port number I'm going to decline this.

Ephemeral ports for localhost oauth callbacks are the preferred method. From the referenced issue, it looks like the root cause is people are misconfiguring the oauth credentials for the quickstart. That's something that can be addressed in the instructions for the quickstart, rather than re-introducing a bug.

Thanks. I'm all for a solution that updates the docs to provide a working solution. I currently don't understand how it could be possible to specify a callback URL in my Google Account that doesn't provide a port number, so I'm looking forward to seeing how such a thing works.
