iptables future-proof?

http://forums.fedoraforum.org – I've been using GUI-driven firewalls on Fedora since the start. Some of them are now old and no longer maintained, so the chances of them working with F12 and future releases of Fedora (and Gnome, even Linux in general) are slim at best. So - is it worth my while to learn iptables syntax/rules so I can set up and modify the firewall at shell level? Will iptables continue to be used going forward? - Is it worth the investment/headache? (HowTos)
