Yeah, but only cause rumored back for season 7 when Sera Gamble was show runner. It was one of her ideas for season 8. Scrapped mostly cause she was leaving. But as far as my theory I think it's possible, that all the remain heavenly host falling was a trigger to SOME kind of event. Maybe even a trigger to an event bigger than the Apocalypse.
