I don't see why Starfleet would be worried about her, either. And I certainly wouldn't enjoy a show where she was forced into service. But then, that isn't SF's MO anyway.
Could I see them treating Seven with hostility, even threatening her or forcing her into SF, right after Voyager's return? Sure, particularly so soon after the war, when SF was depleted and probably steered by more hawkish people. But now... no. If SF was like that, I don't think three of our heroes would have rejoined.
