I've not used the helper personally, but the policy makes sense overall
though. I do have a few questions:

I'm assuming these are needed because qemu-bridge-helper drops
privileges?

Can you explain why this capability is needed by qemu-bridge-helper?

I understood why net_admin was needed, but this one is less clear. Why
does qemu-bridge-helper need this?

I'm not familiar with this directory. What does qemu-bridge-helper need
from this directory?

Is it possible to use this instead:
owner @{PROC}/*/status r,
Thanks!
