The problem is what happens when there are niggling small problems. Do you do the work to handle the problem? If so dev gets a free pass to write unreliable code again. Next what about monitoring? Is it the same as dev environment or all stuff you wrote? How do you test it? So much duplication and overlap.
We get heavily clamped down on access to production by our auditors for Sarbane Oxley reason. Technically we aren't even allowed production data in our dev environment. I dont understand why any organization would allow it. Seems the tech world is still ripe to get sued.
