In short there is a 4 notification icon limit now with the clock on the left, whether you have a notch or not. I often have a lot more than 4 notification icons up (esp since a couple are permanent from background apps) and the rest will just disappear under a dot-dot icon.
Wait. Everything has notch support, even if the device doesn't have a notch? That's odd, right? Given the notch is still an exception? Although they could make the status icons (top) tilt 90 degrees so they are usable from within landscape yet remain on their position
