I think you are confused, there is a difference between "featured Pokémon" (in the announcement) and "actual Pokémon with increased spawns". The list for each event should list ALL Pokémon that have increased spawns, and we tend to leave out evolved forms to reduce over-saturating the list.

Also, Slugma WAS featured in 2017. It was released a few months before the event. Both links above provided prove so.
