Docker applies a default seccomp profile that blocks around 40 to 50 syscalls. This meaningfully reduces the attack surface. But the key limitation is that seccomp is a filter on the same kernel. The syscalls you allow still enter the host kernel’s code paths. If there is a vulnerability in the write implementation, or in the network stack, or in any allowed syscall path, seccomp does not help.
For implementers, backpressure adds complexity without providing guarantees.
