AFAICT, the systemd syntax doesn't exclude the possibility of listing library functions in your syscall list, and having that trigger run-time mutation. And systemd is obviously constructing BFP based on a combination of your list and stuff it knows, if for no other reason than that it has to figure out syscall numbers from names.
