We have this. It's a culture thing. It's not actually possible to force someone to own something till production, but we encourage it and most people follow that.
One of the keys though, is a very easy process from development to code being in production. The more obstacles you put in the way, the less inspired a developer is to own the whole thing.
Not everyone is great at this, and people get frustrated when others don't own their stuff, but typically things are cordial and encouraging, rather than aggressive. But we're still a relatively small place (150 staff, about 40 developers), and inevitably, and sadly, this will change.
