Hi Simon Q! Welcome to the team. I confirmed your Salsa and Debian Developer status, and added approved you for the team.
The "Go book" is badly outdated, so if you read all of it, hopefully you won't remember it all ;) Best source of information on best practices are the mailing list and recent uploads (e.g. https://salsa.debian.org/go-team/packages/golang-github-bgentry-go-netrc/-/commits/master, https://salsa.debian.org/go-team/packages/golang-github-theupdateframework-go-tuf/-/commits/debian/sid) to see dh-go usage and other applied practices.
