Could it enhance code generation ? I could make it depends on 
_Hashtable_hash_traits<>::__small_size_threshold() noexcept 
qualification if so. But I was hoping that the compiler to detect all 
that itself.

Otherwise no, it do not have to be noexcept as it is used to avoid 
hasher invocation in some situations and hasher is not noexcept 
constraint. At least I do not need to static_assert this.
