this is a topic i’ve been heavily involved with because i still consider myself to be someone who prefers using technology at a very beginner friendly level, plus it’s very good when a linux operating system makes you feel right at home when it has a modern desktop environment. this is why i really like gnome, its simplicity and usability is something available for everyone, for beginners and for a lot of other people, but if you had to, say, rearrange xfce or kde for someone who was an elderly person or an absolute beginner so that they wouldn’t have any trouble using linux, how would you do it? (screenshot is my current linux mint desktop, very simple and extremely user friendly!!!)
This would fundamentally break the Unix/Posix functionality of layering file systems. All containerization would break. You would lose the ability to map in one filesystem’s content within another’s. I don’t think the right way to get people used to Linux is to fundamentally break it.
File managers - even the dogshit one you get with Gnome - already register external storage devices in a list that’s shown no matter where in the file system you are. Assigning a drive letter doesn’t clarify anything. What beginner/grandpa is even looking at the contents of the FS root?
