Just wanted to create the PR. We don't have to merge it immediately.

too.

Looks good other than that. I will probably open a follow up PR to cleanup the arithmetic traits.

What would you want to update it to? Remove Kokkos version or update to 3.7 to get another 3.7 build?

What do you want to do there?

Either.

Essentially drop the ArithrmeticTraits namespace and just have using-declarations. We would keep then in KokkosExt:: until eventually the numeric traits get promoted from Kokkos::Experimental:: into the main Kokkos namespace and the minimum required version we support catches up.
