Okay, maybe I should have said _changed_, but I think there are syscalls that get removed from time to time, I just can't think of them.

There is also the question of which semantics older applications should get. Jamie Lokier argued that applications requesting O_SYNC behavior wanted full metadata synchronization, even if the kernel has been cheating them out of the full experience. So, when running under a future kernel with a proper O_SYNC implementation, an old, binary application should get O_SYNC behavior.
