This wouldn't work. sycl::sub_group is an alias to ONEAPI::sub_group, defined in sycl/sub_group.hpp, which in turn includes sycl/ONEAPI/sub_group.hpp. So, I'd either reference an undefined symbol or create a cyclic dependency.
I can add one more alias to sycl/ONEAPI/sub_group.hpp, if you'd like. It seems it doesn't lead to ODR violation or something.

Since these functions are a OneAPI extension, I think the namespace should be |
