@qmuntal if msft Go folks want to be a contributor to our projects, is there a Github team I can add? it'd save you from having to fork.

Yep, this is the team: https://github.com/orgs/microsoft/teams/golang-compiler. We are not using go-sqlcmd directly, but we plan to use it to verify that the MSFT Go toolchain doesn't break compat with upstream.
