Because nostalgia is a driving force for this franchise and BW committed the sin to dare not to rely on that. Which is why even when they cut the National Dex in Sword and Shield, they made sure nobody would miss that Charizard was still there.
They are constantly testing how little they can offer and still have people buy out of sheer nostalgia. That Indigo Disk DLC with the Blueberry Academy looks like it will be very barebones, just an enclosed environment with some Elite 4-like fights, but they made sure to show that all the old starter buddies are back, because they know people will flock to that.
