They should probably just change the default to disallow re-sharing on limited posts. I found the disable re-share option immediately but my wife didn't notice it due to the low contrast of the drop down button on each post.

I'm a little more concerned with the fact that you can see who a limited post was shared with by clicking on the limited link next to posts. It should be pretty simple to figure out who your friends have placed in their circles by looking at who their limited posts were shared with.
