Very nice!

The oldest record of the second command:

 1 | Dep-Install    | dnsmasq-2.66-12.el7.x86_64

I'm guessing that means it was a dependency for something back then. Is 
there a way to discover what? Using "yum history info 1" I see that this 
was the original Anaconda install from 2014. Could dnsmasq be in the 
original minimal disk installer?
