I care more about the way it gets replaced. I constantly learn from my code being replaced, and replacing code myself. However I doubt anyone liking code being pushed onto them. That’s how I feel when someone decides to rewrite code without anyone’s knowledge. They already did the work, so they’re expecting it to be merged in.
The fix for that sort of thing is to have a satisfying, enduring side project where you're the boss: nothing is upstreamed that you don't like.
Then you can stop caring if your code at work gets replaced, and how fast.
