That department becomes the overhead every time since it imposes requirements or work on the team doing the actual creation. They make the teams building the product make changes or answer questions and “gate” releases. Every time you add someone extra things slow down if their whole job is related to reducing risk. Misaligned incentives.
I have worked at multiple of the FAANGs. I know quite well how much overhead these kind of releases take and how much overhead any centralized release team made to “help” end up adding. It’s not just a few small things that you mention.
