Because the 3rd panel looks better when you have dozens of physical properties to track. It also makes retrieval easier because you can get all the physical properties at once, instead of having to read every line.
For an example that small it doesn’t matter, but for something larger it could become a performance benefit.











I’m not an expert, but I thought on Arch you are specifically not supposed to use the discover store because it can cause partial updates which can in turn cause major problems.
However, the point still stands, pacman and the AUR are easy and have nearly everything.
