At any moment now, we won't have 100 Acre Wood returning anymore.
It is all about childhood memories. Adults are supposed to forget about it and just carry memories buried in their hearts of Pooh and friends.
KH3 already had Sora have a moment of disconnection with them because he is growing up.
As Sora gets older, 100AW will be left behind and this may happen anytime now. Maybe KH3 was truly a goodbye to Pooh and we didn't realize.
