I've been playing D&D for 30+ years, and I don't remember that. In fact, going back to 1Ed, plusses and other enchantments were the norm.
I do remember that if someone found a Cloak of Elvenkind (or Elven Cloak) in 1E (and pre-1E), it was the most awesome thing.
The 3E Cloak was pretty watered down until they got to the 3.5 Cloak which was even less spectacular, and finally the 4E Cloak is so mundane and non-special as to not even be worth discussing (and the mechanics for it are poor, +2 at level 7 for Stealth is a snooze, that's almost never going to help a PC be stealthy, 1 time in 10 over normal).
