However, here in The Villages, in a courtyard villa, I have a new high end heat pump. I keep the temp at 71° to 73° 24/7 year round and rarely open a door or window. I also drive a Prius Prime with batteries I charge every night in my garage. Last month my electric bill was $68. At that price, it would be hard to justify a separate heat pump for one area. Turning the house down to 68° at night would cost nothing at all unless the night time temp were above 68°, which is only in the summer, and even in the summer, the sun doesn’t shine on the house at night, so it’s easy to cool the house down a little more.

If cost was the only factor, you might be right.
I can't sleep well unless it is 68degrees or less in the bedroom.
I cannot survive the complaining unless I keep the rest of the house and the bedroom prior to bedtime at 72 or warmer . (My wife also spends a lot of time in the bedroom doing puzzles, devotions, etc.) To cool the whole house from 72 to 68 takes a few hours. So, it is either not cool when I go to bed, or there is lots of complaining about how cold the house is before bedtime. And in the morning, it does not warm in the house for several hours. So I end up having to heat the house to get it to 72 and then cool it. The whole thing is a nightmare.
So, I think being able to quickly cool one room to a sleep temp and not cooling and then heating the rest of the house in the morning makes a lot of sense.
I have been debating doing this for a long time, I would just never post on TOTV to get input.
I am glad someone else did so I could get the idea of the cost and results of those who have already done it.
