I think ultimately, should this direction pan out, it won't matter. In the near term I have to agree with Rakiduam that the fact this is all done at Batman's behest matters and creates problems (the whole dead to the family thing, etc). They are certainly implying, and indeed stating, that it is going to be more than a maguffin. Now, probably they did not really have a choice. The fact is that until they figure out whether and how this new direction is going to work, they can't definitively break ties with Gotham. Indeed, given the nature and histories of the characters involved, they may never be able to make such a break, or desire to. Still, yeah it matters.
