“Break” doesn’t mean repo integrity corruption. It means that you try to merge a branch, and it shits itself with hundreds of conflicts that shouldn’t appear and/or has changes that may partially revert the progress made by other merges.
if they're allowed to push somewhere and make it someone else's problem, that's not their fault
What? This made zeroest sense of the day. Like, I should walk to their desk and check if a feature branch is okay to push or what?
