{{msg-mw|ajax-add-category-summary|notext=yes}} and {{msg-mw|ajax-remove-category-summary|notext=yes}}

I'm just wondering, but are these messages used as an edit summary?

I tried to find where these messages were used, and at first glance they appear to be unused. I tink they may have been part of a reverted feature. Raymond will look into it tomorrow.
