I've already given my vote here, but wanted to share a proof-of-concept C implementation (== copy an arbitrary valid ArrowArray to given a suitable device implementation) of the proposed spec that includes Apple Metal [1] and could include CUDA as well (I did Metal first since Matt already worked up an example with CUDA). The proposed structures were great to work with!
