Why Thunderwave is mentioned as example but is not on the Warlock spell list?

@seekayPHB+SRD Warlock/Pact Magic/Spell Slots uses thunderwave as an example, which is not on the warlock spell list… Errata? That example is misleading. It's slated to be replaced with a spell actually on the warlock's spell list.
