Hi,
The idea is to reduce number of the member of group with privilege and add only users who need this high privlege .Because when a account with high privilege compromised , it can make a huge damage.

I invite you to read this article to get more details about group with high privileage in active directory:

Thank you Patrick.

I've read this article before but I think I was more confused after reading it than before.

In the article, Microsoft says in the second paragraph that "Members of the Account Operators group cannot manage the Administrator user account,... Server Operators," and in the purple note that "This group is considered a service administrator group because it can modify Server Operators".
My english is certainly bad but manage and modify seems to be the same thing, right?

During my tests, I couldn't be able to change anything in Server Operators group (membership, no Security tab, group scope) when I used my delegate account member of Account Operators.

If it's the only reason, I have no clues to say it's dangerous in my situation...
