I'm not sure what you mean by mandatory.

iptables does potentially fork/exec modprobe to load modules.
That can cause a selinux 'domain'/'role'/whatever-it-is-called crossing.
You can do automated inspection of what gets carried across such
privilege changes and any unexpected open file descriptors flag
problems, patches like this cut down on the noise.
