The problem is, for any change, you have to understand the existing code base to assess the quality of the change in the four tries. This means, you aren’t relieved from being familiar with the code and reviewing everything. For many developers this review-only work style isn’t an exciting prospect.

And it will remain that way until you can delegate development tasks to AI with a 99+% success rate so that you don’t have to review their output and understand the code base anymore. At which point developers will become truly obsolete.
