Nissan, uses JATCO CVTs in a majority of their vehicles. They had numerous warranty issues with them early on. I am not sure what kind of problems they are having currently if any, but yes they have made the switch pretty much in their entire fleet of front wheel drive vehicles.
That being said, CVTs are supposed to be lighter, cheaper (cost to mfgr.), provide better gas mileage, and allow engines to operate in optimum RPM ranges for efficiency and performance.
Downside that I see with them is durability, and the driving experience that you found with the Pathfinder.
Almost all of us in North America grew up with and know about conventional automatic transmissions. We know how they feel, perform, and expect the driving experience that they provide and deliver.
Dual Clutch Automatics (DCTs) are another non-conventional automatic that provides a different driving experience. Personally I do not like or care for the driving experience of either, and they have proved to have durability issues too, just ask Ford about the DCT design choice that they made for the Ford Focus.
Unfortunately, the average Joe, or Jolene car buyer today could care less about the transmission or even notice any kind of difference in operation of same.
In 2015, I bought a new compact cross over (Buick Encore) and one of the reasons that I was sold on it was that, it still used a conventional automatic transmission (6 speed). Most of the other brands that I looked in that category at the time had either CVTs or DCTs.
Another downside with DCTs is that most of them use a form of a conventional clutch disc that will eventually need to be replaced from wear. I have no idea how these compare to the wear of conventional automatics, but my gut tells me it will need to be serviced or replaced sooner.
Kudos to you for noticing the different driving experience of the CVT. That makes you an educated driver in my book, but it is unfortunate that the rest of the buying public is not in this camp.
