For reference, in NVIDIA/cuCollections#797 I confirmed that cuda::discard_iterator is now available. We could migrate all existing uses to the cuda:: version in a separate PR.

Ok, it did not show up in my intellisense so I wasn't sure it was ready yet.
I will double check it is available in our version of CCCL

Cuco uses the same or slightly older rapids-cmake (and therefore CCCL), so anything in cuco is also in cudf.
