No, it is a variant of the 737 so using the certification is correct. They weren’t trying to avoid additional certification, it just wasn’t required as it’s a variation of an existing type
It is definitely a variant of the 737, but tacking on those extra large radius engines that the original airframe wasn't designed for and 737 pilots weren’t trained for virtually made it into a new plane.
