For non-free, the priority doesn't make any difference. It cannot be made
essential or required, because that doesn't make sense for non-free.
Basically, everything in non-free is effectively priority "extra". That
said, both packages have their priority set to "standard" in the control
file, but ftp-masters decided to lower it.
It is also worth notice that enabling non-free is not just optional, it is
officially discouraged: non-free is not even mentioned by the Debian Wheezy
installer unless you're in expert mode.
And yes, the only reason to not have it installed by default on every x86
Debian system with an Intel or AMD processor is the non-freeness.
