Further to the point, I would hazard that the majority of linux users don't use wine because its too complex to justify the effort. Very few users for this want to know how they would configure wine to do the same thing, they just want to 'run windows software and games on linux'.
I do the opposite, but for the exact same reason. I couldn't figure out how to use Lutris at all when I first installed Linux, but I happened upon a very detailed guide for setting up a wine prefix (it's just a folder) for the game I was installing. Now when I install a new game I mostly just scroll back through my shell history to see what I did back then.
I just opened Lutris for the first time since then and I think I can see how to use it now. But I'll probably stick to my current ways because it works and really all of it's a pain anyway. Lutris is still invaluable for peeking through the installer scripts, though.
