I wouldn't call Westin a dead brand. Perhaps it could be considered a mature brand, as opposed to newer, fast-growing brands such as Moxy and AC Hotels.

According to Westin’s development website, Westin has 228 open properties, 61 pipeline properties, 82,985 open rooms, and 17,008 pipeline rooms.

That’s very far from dead.

I agree that hotel developers are largely focusing on select service brands for new construction, but Westin would still seem to be good brand choice when a developer has location that calls for a full-service hotel.

Also... considering that 1972 was 50 years ago, I would consider a hotel from 1972 to be a heritage hotel. Westin Michigan Avenue (previously Continental Plaza Hotel, a Western International Hotel) in Chicago was completed in 1972.
