Showing the size of the article in number of bytes would be a very simple thing to implement, and yet useful for comparisment, e.g. for merging pages, for bragging reasons ("I wrote a 10kb article") or to check how long its left until the soft limit 25kb.
Already possible with message longpage-hint (added for bug 21911)
