That's because READ_ONCE and WRITE_ONCE both have additional semantics
beyond ensuring that loads and stores are coherently propagated and
received to and from other CPUs. For example, the compiler is not
allowed to merge loads and stores, although it and the CPU are both
allowed to reorder them.
We don't have similar requirements in Emacs.
