Like everything there are times and places where a sub-optimal solution is perfectly acceptable.
Yes, if your goal is to play video games on 3 simultaneous monitors, or to engage in demanding color correction HDR work, stacked dongles are problematic.
But for many purposes all you want is some extra space to hold static text as reference material, or an essentially similar task, and for that purpose pretty much anything will do the job. I've been happy for many years feeding what was ultimately converted into an analog VGA signal, for gods sake, fed to a 4:3 flat panel from, yikes, quite possibly the year 2000. It's not pretty, but it still works just fine, and it does the job of what's essentially static text display.
