According to the original expansion plans there was plans for a path, just based on guest flow it also just makes more sense, that corner of fantasyland doesn’t have much anyway so it’s not like it’s exposure
That path will exist regardless if they ever use that expansion pad for anything (which is looking more likely since the LegoCo is seeming more and more interested in sacrificing ocean park to have HKDL properly compete with Shanghai) to connect the entire outer ring
