Have you actually contributed to the Go standard library?
Yes, there are people who don't work for Google and can +2 on changes, but you still need 2 Google employees to at least +1 on your change before it can be submitted. This is mentioned in the Contribution Guide [0] and is enforced by Gerrit.
> Finally, to be submitted, a change must have the involvement of two Google employees, either as the uploader of the change or as a reviewer voting at least Code-Review +1. This requirement is for compliance and supply chain security reasons.
