Yes, the kconfig-frontends project is not being developed but there are
forks of this project since quite a few distros and yocto have support for
it.
Is there a requirement that Fedora only adds packages for active projects ?

I explored the kconfiglib project. It is only a library and we will endup
maintaining our own tools for menuconfig, defconfig, etc in the OpenSBI
sources.
The best thing would be if we can avoid adding more tools and scripts
in OpenSBI for kconfig. The kconfig-frontends allows us to do that.
If we have to add some tool/script in OpenSBI then I would prefer
something (like QEMU scripts/minikconf.py) which is minimalistic
and does not add maintenance burden.
