I appreciate you acknowledging that this was a mistake, but as you surely know from your own experience with other people’s mistakes, some mistakes are so egregious that they cast doubt on the intentions of the people involved even if they are corrected later.

To me, “let’s add false attribution to every commit by default without informing the user” falls squarely into that category. I don’t think I’ve ever worked in an environment where something like that wouldn’t have been red-flagged in three seconds by anyone who took even a casual glance. I’d honestly be embarrassed if such a proposal even made it into a public pull request for my organization, nevermind that pull request getting merged.
