One would think so, but if they were already designed as tubeless in 2016 marketing sure would have pointed that out as a selling feature in 2016. Other companies had labelled their bikes to have "tubeless ready" rims at that time.
The fact Giant gives them the same "model#" doesn't' mean anything since this isn't a real model# since you can't just buy those rims like you can from an actual brand name rim manufacturer.
with going tubeless I also go Schrader (please no discussion on how good Presta is), and buy new tires, so just "try it out" is a bit more complex and i rather know beforehand if i should just build new wheels (obviously don't want to build new wheels just for the sake of it). so if someone actually tried the older rims tubeless, would be helpful to hear if they worked like tubeless-rated rims.
