Personally I find just using nftables.conf straightforward enough that I don't really understand the need for anything additional. With iptables, it was painful, but iptables has been deprecated for a while now.
Same here, I'm surprised most linux users I know like to install firewalld, UFW, or some other overlaying firewall rather than just editing the nftables config directly. It's not very difficult, although I've never really dug deep into the weeds of iptables. I suspect many people who have used iptables long ago in the past assume nftables is samilar and avoid interacting with it directly out of habit.
