GR takes the opinion whatever the story is for Phantom Liberty, having Silverhand as part of it will take the focus away from it as players will be too focused on him. I see their point but don't really agree. None the less take a read of the full article, here is a snip;
The main possible issue is that Johnny Silverhand's character arc was already explored throughout the base game. The player could partake in all of his side quests before the end of the game, fully exploring his story and personality. For that reason, his future inclusion could become more so excessive than something that adds to the experience of playing the game. Players already know about many of the things Cyberpunk 2077's Johnny Silverhand did throughout his life, so Phantom Liberty may not add anything of value. With that said, there are some ways that Johnny Silverhand's inclusion could bring some good things.
