It's just a change in epeen value:
From: Have or Don't Have LoD (or w/e title)
To: what date did you get LoD on.
Personally I'm of the opinion that the whole I'm-using-this-title-to-show-how-leet-i-am thing is kinda embarrassing. I generally get the title, put it on for the screenshot, then go back to something interesting.
In a nutshell I doubt they'll ever remove it, they want people to want to (re)visit old instances.
