Salt state for SLES 12 firewall. Use salt.states.iptables?

I have been using the firewalld state module for SLES 15 successfully, but I'm now trying to write a state for SLES 12, which uses the older SuSEfirewall2. Is the salt.states.iptables module the correct approach for this? Wondering if directly inserting iptables rules with that is going to cause any issues if someone opens the yast firewall module later?
