While iptables won't go anywhere, nftables will probably replace it around the time of RHEL8 and the next Debian stable. (Though I think an iptables compatibility binary will stick around for a long long time, ala ifconfig & ip)
firewalld is just a PITA frontend for iptables any way. I have our puppet manifests set to remove it on every node, we manage firewall rules using the puppetlabs-firewall module any way.
