From your perspective, I understand where you are coming from. I imagine that it is concerning to you. The other side of that coin is that there are many people who do not see these changes as dramatic philisophical changes. Personally I think that there is still plenty of work to be done, but I like what I have seen so far.
I certainly recognize the importance of depth and the significance of a strong bench. Trying to convince players who have earned the right to start that they would be better served by playing backup roles to someone who they have outplayed is not as easy as it sounds. From the outside, it might look like it is better for the team, but to most players looking at things that way might work for a while but not for long.
