On Design Approval and Intentional Flaws

Adding an intentional flaw is not addressing the core problem. Consider talking to them directly, pointing out their behavior, and try to get them to only make valid changes. Not just to leave their mark on the design.
Like I said, this may not always work, but it is better for your long term relationship with your manager.
Is it? I think you're making a pretty big logical jump here. It's just as easy -- maybe easier! -- to argue that letting your manager retain his Feeling of Importance (a la Dale Carnegie) is the better way to maintain a good working relationship.
Only you can know whether your husband or wife would be happy if you answered "How does this make me look?" with "Fat." Same principal applies to telling your manager you're faking things to soothe his ego and need to tweak… regardless of how diplomatically you put it.
Every problem is a people problem. Managing managers (stakeholders, whatever) is just the same. We "fixers" tend to think that what we're really doing is fixing a problem or building a new thing, but that's rarely how the people hiring us look at it. They're the star of their own show (just like we're the star of ours), and they are doing it for their own reasons. Often those reasons have to do with feeling good about their contribution, looking good at work, leaving a mark, as you say, or CYA, etc.
If you don't understand that, and don't want to deal with it, then being a consultant or employee is a bad career choice!
