That's a very good reminder for all of us. I wouldn't mind making it mandatory for undos. Leaving a edit summary explaining the revert is also good for searching consensus. Building consensus through editing is a good way to improve articles but can't happen without edit summaries. Quite commonly agreeable result can be achieved, without any further discussion on talk page, with just few edits. Just be sure that editing and comments are constructive, edit warring is not accepted. See also Help:Reverting.
