I don't see how that really meshes with the GL writer apparently never hearing about this until the announcement and Conrad tweeting stuff about using more if Diana's old villains. And Johnson telling people not to worry.
Not that any of them have any serious pull. But hopefully it indicates that the solo books can just function as normal. Literally nobody is asking for any of this, I would hope the company would be smart (ha!) To not force it on an audience who has no delusions that any of these characters will stay dead
