I'm fine with ray tracing being left out or minimized at least for the first model.
THAT is an example of a feature that could be added to later Switch 2 models and not break compatibility between systems, you could have a Switch 2 Ultra or whatever that's capable of ray tracing but otherwise the game is exactly the same (or have a home dock that enables it).
You can cheat a lot with baked lighting solutions anyway to approximate something closer to ray tracing anyway.
