I didn't think you were concern trolling, sorry if it came across that way. My impression of that village was that it was specifically for people who are easily disoriented and lost and need special full-time care, not for most elderly- or even very mild, high-functioning dementia cases who can still handle 'normal life' well.
Definitely better than the current option (hospice, hospital, etc). My grandfather died of alzheimer and even though he was in the best facility my mother/aunt could find once they could no longer ensure his safety and care, it still was a very depressing place. Many other residents were aggressive and very noisy which stressed-out my grandfather who was a quiet and withdrawn personality even in sickness. Since they were all in the same building, there was no escape from the atmosphere. A village sounds a lot less claustrophobic.
