I'm not sure whether you've missed "swapon --discard", which switches on discard_swap_cluster() just before we allocate from a new cluster; or whether you're musing that it's no use to you because you want to repurpose the swap cluster to match erase block: I'm mentioning it in case you missed that it's already there (but few use it, since even done at that scale it's often more trouble than it's worth).
