Just ran a minimal install on a box here. Ended up with about 310 
packages and a

rpm -q --whatrequires "python(abi)" --qf "%{NAME}\n" | sort

gives me this list:

authconfig
dbus-python
firewalld
libselinux-python
newt-python
pycairo
pygobject2
pygobject3-base
pygpgme
pygtk2
pyliblzma
python-decorator
python-iniparse
python-pycurl
python-slip
python-slip-dbus
python-urlgrabber
pyxattr
rpm-python
yum
yum-metadata-parser

So there's quite a bit of other stuff that still requires python as well 
apart from firewalld.

Thanks & regards, Phil
