But even the people of Johto, Hoenn, Sinnoh, and Unova do not "covet" or "revere" their regions' legends that much. They discuss them, yes, but that is because they are a part of their regions' histories. There are few that even actively practice worship for Legendary Pokémon.
It's not about worshiping, it's about keeping the myths alive. The legendaries to the people of Johto and Hoenn were part of the region's identity, they actively kept the myths alive through stories and whatnot to the player meanwhile Kalos people don't even mention it. Unova didn't as much as Johto or Hoenn but the legendaries were still mentioned often enough to give a sense that the people knew of them.
