Sorry for the delay here. I'm a bit hesitant about to handle this, I would ideally want to return views with something like wrap(View, x, to_dlpack) and error with the default wrap method (the last past being what you are introducing here).

@pabloferz, thanks for the discussion, I'm considering some similar question these days.

But I think wrapping a subarray could be a bit difficult here if we only have the information from the dltensor. Because we need to firstly wrap the parent array of the subarray, then compute the indices which could return the correct subarray.

Also, in some cases this problem could be complex. For example, dltensor is some transposed ndarray, like transposing a 3D tensor with permutation (2, 1, 3). I'm not sure subarray could handle this situation.😔
