Lore was an extreme threat to everybody on every occasion he showed up.The complete lack of mention of Lore is very jarring, especially as his body was in Starfleet custody and they'd have access to him to recreate androids. Also, strange that there's a general lack of security in Picard's vineyard, or even the middle of a city apparently. Especially someone like Picard who has made enemies all over the galaxy, you think he would have a lot more security at his vineyard that Dahj would feel relatively safe there and not feel like she was endangering Picard.
After the last time, I'm pretty sure that Data made sure that Lore would never be able to endanger anybody ever again.
Even if it meant destroying Lore's head.
