>Thinking "for a fact" that users will do something is a perfect way to make several of them unhappy when they want to do something else :-P.

My point is those users will be unhappy anyway, they choose to break their own system. There is little reason to try to accommodate them further. The alternative is always going to be don't use that WM or don't have scaling support. It is not superior as you are always faced with this choice. That is the choice you get when you want to use legacy apps and WMs which is the only real reason to still be using X11.
