It can be removed from vmlinux, and be folded into the crypto API's generic implementation where it belongs, which then can be built as a module or not built at all, depending on configuration. Please see the 3/3 patch in this series to see what that looks like: https://lore.kernel.org/lkml/20220114142015.87974-4-Jason@zx2c4.com/
