Yes, in the sense that non-ETOPS twins can operate longer routes while staying near diversion ports, they do not need ETOPS. But on the other hand, there are a number of not very long routes where diversion ports do not exist - ocean crossings and remote areas. A twinjet with a range of, say, just 800 miles would not need ETOPS - even if there are no diversion ports, it is always within 400 miles of either origin or destination, and therefore at jet speeds less than 60 minutes. But the E-jets have longer range, and therefore need ETOPS.
E-190 got ETOPS 75 in Spring and expects to get ETOPS 120 early next year.
