The major problem I see it is less that Superman is being Superman 24/7 (at the very least, it's been explored in expy characters like Hyperion, Mr. Majestic, even Invincible to some extent) or the loss of Clark Kent (though the metaphor of "any man can be a Superman" does lose a lot), and more that Bendis is trying to have his cake and eat it too by having him still be a writer, hanging out in the Daily Planet and investigating a corrupt mayor.
Typically speaking, Superman without the identity is done to focus on the big picture, trying to focus on making worldwide change rather than just leading by example since he now has more time in his hands now that he doesn't have to worry about paying for his rent. While I suppose this is being explored with the whole founding of the United Planets and Superman being President of the Earth, it's not going to be the thing that Superman is focusing the majority of his attention on (unless rumors about Jon becoming Superman 2 are true, but I digress), it's still going to be this juggling act of responsibility. Superman is still the "cosmic" book and Action Comics is still the "little guys" book. Granted, it's probably simpler in this than having to contrive Clark out of town half the time, but I honestly find letting only the Daily Planet staff into the secret more interesting than this status quo.
Realistically, no one would blame Superman if he just moved to the Fortress of Solitude, but he's not going to do that because no one, least of all Bendis, wants to lose that everyday human touch where Superman helps out his neighbors. In other words, it's what Stan Lee called "the illusion of change": all the pieces are in the same place, they just look slightly different.
(And odds are, when Bendis leaves, be it one year or ten, the next writer will probably just handwave the secret identity back faster than you can say "Purple Children" simply because that human element is a lot easier with Clark.)
