Why hasn't "Qubes way" become standard?

I agree to disagree ^^ Before theming my OS/apps, I make sure they work properly !
Another car analogy : do you prefer a car that drives properly but looks bad, or a good looking car which never leaves the parking lot ?
It would help new users to be able to use really easily (think “click-click”) all the new automation methods unman and the team are creating (like How to manipulate the Qubes OS menu via salt?).
There has been a new Qubes doc showing “use cases” for different people. Now wouldn’t it be nice for them to DL the corresponding version ? (BTW, the theming could apply to all of them).
