On x86, memory_order_seq_cst is not of practical interest because of the performance impact of the mfence instruction required in the implementation of the store operation.
Maybe it's a thing for college beginner class. ;)

Music to my ears! And please don't keep your views secret!!! It is always better when I am not the only one defending non-memory_order_seq_cst atomics. :-)
