• Reviewers Assigned
• Squashed all commits, uses message "Merge pull request #XYZ: [title]" (coding standards)

Disabled the unparam linter for now - either we should actually use it (and not just write a bunch of // nolint comments) or we should ditch it. Maybe we can add it back later when the code is more stable.
