Weston Pace commented on ARROW-17820:
-------------------------------------
Could we do this by running the kernel on the child array? For example, if we
have LIST<FLOAT64> we have a parent list array with one child array. We could
run the unary kernel on the child array. I think it would only work for unary
kernels however.
