My 08 sienna had it kinda. It didn’t have sensors in each wheel, instead it guessed based on relative rotation of the tires at speed. This was problematic; lots of false positives but it was easy to reset. It caused undue concern but it did actually work too (true positives).
Sensors are their own headache. They must be taught to the car computer which requires specialized equipment. I swap my summer and winter wheels myself so had to buy the $200 thingy and go through the headache of learning to use its terrible interface. They are also another failure point; one of my sensors died prematurely so I have to take that wheel in to fix it.
