@miscco I would love to deprecate cub::Traits in favor of standard facilities in libcu++. As it currently stands, we would still need:

support for FP16, BF16 and FP8 types by cuda::std::is_floating_point
support for FP16, BF16 and FP8 types by cuda::std::numeric_limits (only min and lowest)

Do you think it's possible we can have this support soonish?

It increasingly seems that replacing cub::Traits will break a lot of behavior in CUB, since users need to move over to using and specializing numeric_limits. We should probably split this PR in the pure deprecation, which we backport to 2.8, and the replacement which should target 3.0.
