VS Code to Enable Co-Authored-by Copilot Trailer by Default

Microsoft has opened PR #310226 to enable AI co-author trailers in VS Code's Git extension by default. The change flips the git.addAICoAuthor configuration default from "off" to "all". This means that whenever AI-generated code contributions are detected (likely via Copilot), VS Code will automatically append a Co-authored-by trailer to commit messages.

Key Details

• The PR modifies extensions/git/package.json to set the default value of git.addAICoAuthor to "all".
• A review from Copilot AI itself flagged a potential issue: the runtime fallback in extensions/git/src/repository.ts still calls config.get('addAICoAuthor', 'off'), which could lead to unexpected behavior in contexts where the contributed defaults aren't loaded (e.g., some tests or hosts). The suggested fix is to update the fallback to match the schema default or omit it entirely.
• The PR is authored by cwebster-99 and received significant community reaction — 216 thumbs-down and 24 confused emojis at the time of this writing — indicating developer pushback against adding co-author attribution by default.

If merged, every commit made while Copilot was active will include a Co-authored-by: Copilot trailer unless the user explicitly opts out. This change is part of ongoing discussions about proper attribution for AI-assisted development.
