This is true, However, I think most people just use the default option. And as Khaled has never mentioned that he uses those settings, I have to presume that he uses the default layout too.

It would make sense if the settings you reffered to were made default, And a post was made by the moderators to encourage people to use them. Or perhaps that requires to much effort...

Also, I think anyone who says "use the search feature", but doesn't use the settings you mentioned, Has got a real nerve. And i'm sure that accounts for a lot of people.
