Focus by mechanics has the same issue... When you look through the viewfinder you do not know "where the focus is" (in distance). Why do you want to know how far focus is, when you can see what is in focus? Does that ever matter?

I don't use hyperfocal focusing but those who do, really care for it.
The only times I misse the focus scale is when doing night shots once I was shooting long exposure shots on the beach on the beach, it was dark , I could barely frame in the viewfinder, also using my 8mm Samyang fisheye I totally rely on the focus scale.

Take my word if you were shooting there, you would really need a lens focus scale of course, dunno if the photographer used it here or not A7iii does show focusing distance in the LCD though, but if you are using an SLR or if your camera doesn't show focus distance and the LCD is black or near black in those conditions, focus scale is the easiest approach
