I'm pretty sure the Outcast-worship thing was in vanilla. It's not explicitly in the campaign, but if you read the rumors in Planet Malta's bar, some will refer to the Nomads as "Great Spirits" who are honored by burying the Outcasts' dead around the Omicron-90 Jump Hole with the ships facing the Jump Hole.
FYI, there are many conflicts between the campaign lore and Discovery lore, especially regarding the Nomads.
