If you replace "-matomics" with "-mbulk-memory," I plan to duplicate the logic for items 2 and 3 above, but not 1. For bulk memory even more than atomics, there is a legitimate usecase for enabling it even in single threaded contexts (namely getting to use memory.copy and memory.fill). I wonder if consistency with how bulk memory works is a strong enough argument for dropping item 1 for atomics as well.
