beware, some cultures are territorial in nature and this kind of hard ownership will make people slap you if you ever try to improve things as they come.
i'm in the camp of improving things regularly without hesitation but again this can devolve. another way it can turn sour is when the team is made of people too different from each other. one improvement from someone pov is a waste or even a regression for others .. then it's a 'who decides here' conversation.
that said when you have a cohesive group all focusing on pushing in the same direction then it's bliss
If you're skilled enough, sometimes you can even force the culture to change. It can be painful and not all battles are worth it, but it's doable.
Then that's a bug in the organization. If you're senior enough you might make the correct boss take notice and signal this defect globally (no fingerpointing) to him/her. If they don't care or answer you know where you are now and know if you consider that you want to leave or not.
