Looks to me like it is a education concern more then anything. I'd guess those that have a concern with them don't actually know they can be bypassed. OK Admin roll out sticky 101
Let me know what specific size graphic you'd like to see and I'll resize it up and/or find a better one.
Love the sticky notes. However, most people seem confused by them. Suggestion -- put a little icon next to the "sticky note" post in question that becomes a link if clicked to an explanation of what it is, and says "sticky note" when the mouse passes over it. Just like you do when a post is restored there's a green recycle icon that says "restored post" when the mouse goes over it.
