Over optimization is a tiny signal of badly written content.
From my experience, if you write good content and provide real value which can be recognized easily, over-optimization doesn't really matter.
If you provide bad content with no value, over-optimization is just added to the pile.
Working on de-optimizing wouldn't give you any good.
That's it.
