When these "modern" OS-es start, the clean desktop is shown,
meaning the user knows it is there, and for some reason the starting state is off limits if there is one or more programs open.
elementaryOS also does this.
Even the keyboard shortcut to show the desktop is removed.
The section isn't even there anymore.
Would be interesting to see what kind of problems people think they are solving by implementing this.
It is 100% against convention of anyone touching a computer or device the last 30 years.
The upside seems to be not accidentally minimizing something you are working on.
It is also not how the system the user is familiar with and is using has functioned in the past. For my own sake I will say this makes me think of something I know I can use, into something where I think I can't figure it out and no change was needed.
And no, it just isn't possible anymore. No explanation.
The mind compartmentalizes information in structural hierarchies, and the spatial awareness to keep track of this is something you can do with cognition, but the ability to look at a clean slate actually has function.
It is the closest thing you get to seeing where your files are by default.
Yes, that place someone decided no files are to be shown,
before they decided file hierarchy is something the user shouldn't do.
There is a serenity to having just a clean slate to go back to.
It is as familiar, and not having what you are doing visible on the screen is useful.
It also has the benefit of vested interest and familiarity in that the user often changes the desktop. Thus making it their machine.
