ARt is great af. Well, according to the lore the Hakurei family separated the human world from the "youkai" world aka Gensokyo. It's implied that Yukari had a great importance is this conjuncture since shes the one that control borders and was always close to the Hakurei family through generations. Maybe the author changed that up a little bit and put all the work on Yukari's shoulders, creating a new backstory for Reimu since she's obviously not the first Hakurei miko.
EDIT with some infos: "The barrier was first created by humans in Meiji 18 (CE 1885), and later reinforced by youkai. While the idea was at first highly controversial among youkai, and led to much infighting between them, it is now almost universally accepted. Yukari Yakumo is widely acknowledged as the architect of the barrier, and is said to have first motioned for it around 400 years before its actual creation, though Yuyuko Saigyouji has speculated that not even Yukari could create a barrier of this level by herself."
