As I've said for kiosk check-in, I see this as a bad thing. Disney at least still claims it provides great service and that service sets it apart from rivals. As such they should look for every opportunity to provide service. This sort of thing is an admission that they aren't able or willing to provide great service--the kind of service that is friendly, helpful, and timely enough that you feel better for having received it, as opposed to skipping it just because you can.
And I know many people will say, it's optional, and maybe some of us just want to get to our rooms, but to me that's like wanting to skip the stretching room at the Haunted mansion to get on the ride quicker. Plus, I'm expecting that if things like this take off, they will reduce desk staff. It's like how Fastpass is now effectively required at some attractions that didn't need it before they had it, because now the stand-by line is so long.
