Create a new page, then look in Recentchanges. The link to it has a &rcid= stuck to it. Yuck. What if one is a slow reader, and by the time one gets around to clicking on it, the page has changed? This is just one of the reasons not to have the rcid= stuck on the back especially for the first instance of new pages.
As far as I understand, "rcid" is only attached to diffs and new pages if the user can patrol and the edit/page are unpatrolled.
