I am only dropping the requirement of using it in order to call get_kernel_max_sub_group_size_for_ndrange or get_kernel_sub_group_count_for_ndrange when the extension is supported. Because I don't see why this would be needed especially that all other functions from subgroups can be called without the pragma https://godbolt.org/z/MYavchPT3.

True, I have forgotten about those. :)
