The osbuilder Fedora support doesn't work with distro kernels.  It also
doesn't use the latest Fedora release (30).  It's probably not used much
and removing it would be fine.

I haven't tried.  In theory systemd is just a dracut module that can be
disabled.  Maybe it can be replaced with a kata-agent module that acts a
/sbin/init instead.  This would result in a smaller initramfs.
