Beverly Crusher was a major part of Picard's life. It makes sense to have her in PIC. She's the one main character who wasn't mentioned or referenced in the first season, aside from Wesley. She's conspicuous by her lack of reference or mention, and remains unaccounted for. IMO, there's a story-reason behind it. I'm not saying I think she's dead (like I thought before), but maybe there's a kernel of truth in the AGT Future where something happened between Picard and Crusher. Not necessarily marriage and divorce, but something.
