Backwards compatability is A Good Thing.
I've got binaries on my system that are linked against libc 4.1 (and
possibly some that are linked against libc 4.0; since they are
static, it's hard to tell) It would be unpleasant to have to
manually patch system calls back into the system so that these
binaries would continue to run.
