It's less work for someone to manually hire a rogue once they are available than it is for someone who doesn't want a rogue to get one anyway and have to go to the trouble of getting it killed. Of course, Blizzard decided to hand-hold the new players, so the rest of us end up having to put up with it.
Furthermore, even if I want a rogue merc, there's a chance I won't get the one I want through the auto-hiring mechanism. If that occurs, I have to go to the trouble of hiring a new one. Better to just kill the auto-hire feature and let players be responsible for hiring or not.
