Well, no not really. This basic panning theory. Do know that the 'precision analog panner' AlexB supplies with MFC is a little special analog panner device he created himself and then sampled. Any 'openness' it might give you is probably because of this
Basic panning: When you put a signal all the way on the left side, it's only on the right speaker. When you put a signal all the way on the right side, it's only the right speaker. How do you get something in the center? By placing it on both the left and right speakers.
But what happens when you have two signals and you add them together? They get louder!
So without any pan law, a signal that is centered is louder than the same signal on just the left or right side. Consoles had pan laws built in so that this volume differences is compensated. So when something is centered, the volume is lowered to compensate for the fact that it are two signals added together.
Without any pan law, if you start panning something hard left, it would go to the left but also loose in level (and energy). The idea of a pan law is that if you pan something left, you really hear it going to the left without anything else (like level) changing.
Reaper defaults to no pan law after a clean install, but can be changed (in project settings) to be -3, -4.5 or anything you want (boosting the sides or lowering the center), and can be altered per channel (and on the master). It's normal to have the same setting on all channels though! For bus-groups I sometimes change it, but that's it. I know Presonus Studio One 2.6 has a pan law of -3 that can't be changed (and I think cubase will have the same then?). Old N**e desks had -3 while (old) S*L desks had -4.5?
Anyway, don't confuse the effects of pan-law (proper panning without volume loss) with any analog magic the AlexB panner might add
