The reason we have the rule is because threads that die don't really need to be revived, unless for a good reason. Also the OP can always request for an unlock.
At one time, there was an auto-lock on the forums on old posts, however, that is neither here nor there. Forum posts are dynamic, they come and go, like mile posts on the highway. It's fairly rare that anyone goes down a highway, and, at random, leaps backwards for 25 miles or so. Unless they are in an episode of The Twilight Zone. :)
