The question is then what are you running that requires rpcbind?   On my  
systems
without an active NFS service it isn't enabled or running.

rpcbind is directly or indirectly required by libvirt. dnf wants to remove  
libvirt, if I tell it to remove rpcbind. I'm using KVM to run a bunch of  
Window VMs.

That answers the question of why I have rpcbind installed.

Looking at why it is enabled:

[root@monster multi-user.target.wants]# cd /etc/systemd/system/multi-user.target.wants
[root@monster multi-user.target.wants]# ls -al rpcbind.service
lrwxrwxrwx. 1 root root 35 Nov 19  2011 rpcbind.service -> /lib/systemd/system/rpcbind.service

My rpcbind service seemed to have been enabled in 2011. Its current vendor  
preset is "disabled". So, I guess, it wouldn't be enabled today, by default.  
Was it enabled by default in 2011? No idea. What does disabling it would  
mean, with respect to libvirt, and any guest VMs? No idea.

... Hold on a second. Digging through Wikipedia, Fedora 16 was released a  
week before the rpcbind's enabling timestamp on my server.

Grabbed https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/ 
16/Fedora/x86_64/os/Packages/rpcbind-0.2.0-15.fc16.x86_64.rpm

postinstall scriptlet (using /bin/sh):
if [ $1 -eq 1 ] ; then
   # Initial installation
   /bin/systemctl enable rpcbind.service >/dev/null 2>&1 || :
fi

Well, that answers that. Happy New Year, everyone!
