Current nftables-0.9.3-26.el8 is pretty far behind RHEL9 despite 83 distinct backports applied on top. Use the chance to push RHEL8 to a newer base, reducing maintenance burden in the future. To reduce involved risk, take what's currently in RHEL9. This will require a rebase of libnftnl package as well.
