I think that a lot of people would probably hesitate to remove mentions of their keywords/phrases from a page when adding content. I have thought that way sometimes.
gouri, you are addressing keyword density and not keyword stuffing by adding more text. I don't think keyword density has again become a factor now. For eg., some people try to start each sentence with the keyword they target. That is keyword stuffing.
Though I appreciate this post and brinked's suggestions, over optimization penalty in general is a myth...off-course one need to avoid keyword stuffing and anchor text targeting...
