It's about the blend of both. Edges, line, positions are always going to make a difference, and they're still part of the GOE for technical elements (you don't think Alina is doing Tano lutzes just because the arm is beautiful, do you?). That said, I don't think anyone is worried about technical ability being underrewarded anyway, especially in a system where Mirai falling on a triple axel (5.5) still gets more points than, say, Alina's perfect double axel (4.56)
