python3 is a hard requirement of dnf so can't be removed [1]
grubby is also required for kernel installs on Fedora. For too much
detail see I1a6e45d04755515286b3d49f8280c16b527e2f48; but the kernel,
via dracut, now has this as a "recommends" due to people removing it
and making unbootable systems.

As described in the comment, there is a dnf equivalent of this command
that doesn't require us installing yum-utils (which drags in yum on
dnf-only systems such as f23)
This is a small consequence to this -- due to us not installing
yum-utils some installs will now be completely yum free. This causes
a breakage in ironic-agent 99-remove-extra-packages where we remove
the yum package. There is a long-standing bug/feature where missing
packages in a group of packages do not cause yum/dnf to exit with
failure, but uninstalling a single package will. Because we have made
the systems yum-free, the uninstall of yum can fail in this corner
case.
It has always been like this, so I'm in favour of the "ain't broke"
approach. To work-around this, I have just put yum into the existing
list of packages to be cleaned up. I have added a note to the yum
installer taking note of this behaviour for future reference.

This patch is reducing the size of the ramdisk image generated by the
ironic-agent element. It does remove extra packages (graphical stuff,
dev stuff, miscs, docs, etc...) and purges directories that are not
needed for a ramdisk (like /boot since it boots using an external
kernel)
Currently it was tested generating a Fedora 22 image and reduced the
size of the final image from 464 MB to 211MB compacted (54% decrease).
I was able to boot a VM with 1.3 GiB of ram instead of the previous 3 GiB
needed.
