SAE (the Society of Automotive Engineers) just formally adopted NACS as preferred standard [1], so CCS1 may have indeed "lost".

Conversion of existing CCS1 chargers was one of the things SAE supposedly considered in making the decision. NACS "speaks CCS software over Tesla-designed hardware" so it's mostly just a hardware change at one end of the cable. (Tesla made some smart decisions when they decided to standards track NACS.)
