They are pretty much killing the idea of using regexes to linkify URLs without the scheme in plain text. Given that Chrome has moved to dropping the `http://` from its address bar, and many people already skip it, they are probably going to break a lot of linkification code in comment forms and the like. Sure, people "should" know to type the `http://`, but many people just don't know about that or don't remember, and there's a lot of encouragement not to.
