I think that would sacrifice far too much flexibility. Even without Capsicum, it would be worthwhile to be able to wire up a static seccomp-bpf filter to enforce constraints such as "you can open files under fd#5 for reading, but you can only write to files under fd#6, and you can't do any global lookups."
