They have subsequently given up and consider it a firewalld issue. I think if I include jail.conf in both subpackages %post should work fine (instead of %posttrans). It will be marked %config(noreplace) for updates and if the packages are switched out, the sed substitution should work fine or no-op. I'll add the nftables package as "Recommends:" to the main package so it will get installed by default and come up with some kind of virtual require / provides for both subpackages to make sure one is installed.
