As long as people can wear the rings I don't care if they only start working at lvl 11. Those kinds of magic items are like really high level monsters. Realistically speaking, your lvl 2 3.5 characters could encounter an old red dragon but from a DMing POV that equals "rock falls, everyone dies". So most adventures don't feature that kind of encounters.
If I as a DM know that magic rings don't work until lvl 11, I wont introduce them at lvl 4. If I introduce them it is easy to do a LotR-move: The ring gives some minor power until it is worn by someone with the power to wake it's real potential.
IMO many people have lots of problems with things that most likely will never come up in the game. Sort of like the discussions about the gender of angels in medieval times.
