If you look at it thru non-fan eyes, tho ... how incongruous is a boat ride thru a functioning greenhouse in a park (soon to be) filled with IP-based rides? It only makes sense as a nostalgia fix for an EPCOT that no longer is.
Something I saw on DisTwitter yesterday, can't remember who--"you can't have an open casket funeral forever." Living with the Land is as much an outdated relic of another era as the Leave A Legacy tombstones. Take that out, can put character dining and a new QSR anywhere.
No idea if this particular rumor true or not--but assuming Mickey has the cash, these being gone by 2026 seems a safe bet.
