You talk like once you enable EAP, you are forced to sit back and do nothing. It's pretty trivial to stay as alert as if you were in full manual control and see how the car performs autonomously in your area. This is my default mode of operating the car whenever I've tried out EAP on local roads. It definitely has tough times handling some conditions, and I've had to override a lot. I anticipate the same thing when the car attempts intersections autonomously. I'm still responsible for the car and will make sure I'm not endangering other people's lives.
So, my take is that all these new features are part of EAP and is still level 2 in quality. At some point when the NN is smart enough for level 4, having HW3 will let you enjoy these same features at level 4, while people with only EAP will still have these features but at level 2.
