So why did this feature get rushed out without proper testing? Are you claiming that not having this happen automatically for the commits where Copilot actually co-authored them is so urgent that it was necessary?

I'd argue that this was extremely non-urgent and the fact that this got rushed so sloppily is a giant red flag about the priorities of you and your team. You asked about constructive criticism, and yet you're also acting like this is a one-off innocent mistake by only addressing what you've done to roll this back for now and address the immediate issue. I don't buy the premise that we could trust that this was a mistake made in good faith when it's something that you clearly should have known people would be so upset about if you got it wrong.
