That's because the DT Swiss patent expired, they'd probably been waiting around for that for a while, Mavic moved their entire range from their 2 pawl design to the star ratchet design.
I've seen a few designed tbh, including a magnetic one. Cant be bothered to look anything up. I'm on the opposite end of the scale with a freecoaster anyway, it's more than an eighth of a crank to engage 😅
About the only useful things that have changed are taller bars, shorter cranks and better working freecoasters.
Actually saying that, carbon frames, new ratchet/drive/hub designs and through axles on the racing side of things is nice
