Good article regarding fog lights. I don't think it applies entirely because, again, these lights shine into the same direction as the high beams, just at a slightly wider angle.
Further down in the article, there's the following paragraph, albeit about old-fashioned low beams, though the sentiment applies exactly to my high beams:
In the past, many US-specification low beam headlamps tended to provide relatively low, arguably inadequate levels of light in the foreground and to the sides. They created the impression of a "black hole" in front of the car, with essentially the entire beam concentrated in a narrow band or ball of light thrown into the distance. With headlamps like these, a decent argument can be made for the use of fog lamps to fill the "black hole", that is, to add-back the missing foreground and lateral-spread light when driving at moderate speeds on dark and/or twisty roads. Of course, lamps to rectify inadequate foreground light must be thoughtfully and carefully selected, correctly aimed and properly used. Otherwise, they're useless at best and dangerous at worst.
I think it really boils down to the use case. I'm primarily concerned about night time driving on dual lane country roads on hilly terrain with frequent twists, driven between 35 and 45 mph. Seeing far into the distance isn't a main concern because you cannot see around curves, yet low beams, even properly aimed, do not illuminate far enough. Glare for oncoming traffic also isn't a concern because these are wired in with the high beams; so they're turned off anytime there's oncoming traffic.
