There's some misunderstanding here. On Linux desktop, Chrome does its API filtering via BPF (in seccomp) and Namespaces, with a fallback (via a setuid wrapper!) if those are not available.

But you need IPC if you need to get the remote party do something on your behalf outside of what the sandbox allows (or just to transfer data, really), and that's used extensively on *both* platforms.
