The PR description says this “Fixes #1639”, but #1639 describes adjusting the Go Updatecli policy to preserve container image SHAs when bumping Go versions. This change removes the Go Updatecli policy entirely, so it doesn’t address the issue as described. Consider removing the “Fixes #1639” reference or updating the issue/description to reflect that the Go auto-update is intentionally being dropped instead of fixed.
