Yes, but in practice, do ruler/dukes care about this? It does not seem like it from my point of view.
It makes it easy to appoint nobles with claims. And when it's a 3 day journey to the region to appoint the noble you would prefer, many times people will accept their second choice because it's just more convenient. Also, avoiding that bit of discontent can be very helpful when the region is already marginal.
Also, I forgot to ask before, why was the buying of lordships (in your own realm) removed? It seemed to be excellent for creating innovative and exciting events.
It's the same as the "question nobility" thing. It was widely misunderstood by a significant portion of the players, and caused lots of problems.
