Just a while ago, I accidentally kicked the wrong person from a party because they looked very similar to the one who DCed (The one I kicked was the one who asked me to kick the DCed knight). While it is entirely my fault due to lack of focus, I figured it would be easier to have this in the UI. For one thing, it'll prevent us from having to walk through traps, shankles, fire and whatnot just to make sure the guy who stopped moving didn't disconnect.
