I agree, my point was more like I'd rather not add the syscall for recvmmsg only right now, and others later, and instead of an all-or-nothing approach, ie, add all the syscalls at once (while keeping the socketcall around of course). That would make glibc work easier not having to track syscall availability on a per-syscall basis etc...
