For one thing, this version of OMAC might show us the implications that Paradise Island might have to the greater world of the DC universe, which I think is really cool. I mean, a whole civilization made of amazons must create various movements and iniciatives, both in support of and against. In this case maybe it's about weaponizing those female ideals.
The fact that it's a technological character tied to the Wonder mythos is also really cool. Plus it's a character that challenges plenty of gender norms, which is something the world of Wonder Woman really needs more of.
