Code review makes this a lot less scary. Honestly it seems like mostly a win. A while ago at my day job, a moderately technical manager on another team attempted to contribute a relatively simple feature to my team's codebase. It took many rounds of review feedback for his PR to converge on something close to our general design guidelines. I imagine it would have been way less frustrating and time consuming for him if he could have just told an AI agent what to do and then have it respond to review feedback for him.
