This is bad. I need to start Monday warning my team about this and installing validation hooks in our repos that catch any commits with this. We don't have a non-AI policy, but we have an "approved AI" policy due to data security, and having all your commits say "Co-Authored-by Copilot" is more or less the same as as "I ** on infosec". We also have a "short commits message" policy, and that "Co-Authored" thingy takes characters.

Sorry about that, it's being reverted: https://github.com/microsoft/vscode/pull/313931

short commit messages, but you would usually allow details in the details part of the commit message, right? Which is where this goes?
