I have a feeling the thought process was something more like this:
"Ok, there has never been a very good way to determine what character a monster will go for, any ideas?"
"What about an aggro system like in several MMOs?"
"Not sure how that will work for D&D precisely, but let's see if we can use it to make a better game"
*5 playtests and several revisions later*
"OK guys the aggro things was only so-so and just feels like it's adding more restrictions to the game, which we're trying to remove in the first place. Great try tho, we found out one thing that definitely doesn't work."
If our game developers weren't doing things like this, I agree with others that I would be disappointed. Try everything, keep what works well and makes the game more interesting and fun. I don't care if you found something useful to borrow from Vampire, GURPS or Monopoly, if it works well and makes D&D a better game*, then make D&D a better game already

*It's already a great game, but I see room for improvement and obviously the 4E team does too.
