One idea is to push into iptables some infrastructure so the script
can inquire iptables on available options. This would be simple C code
to be places on every extension to print the options. Then, add a tool
like iptables-completion that you can use to inquire what is possible
to get as options. Thus, we get a generic script that inquires
iptables, instead of having them all hardcoded into the script.

One more thing coming into my mind:
A new tool would not be backwards compatible.
While the shell completion could be used with old versions up to when the -S parameter was introduced. When commenting out some unsupported extensions in their definition array, it'll be suitable for vast parts.
