I have seldom come across unix multiuser environments getting used anymore for servers. Its generally just one user on one physical machine now a days. I understand run0's promise is still useful but i would really like to see the whole unix permission system simplified for just one user who has sudo access.

I guess it depends on the servers. I'm in academic/research computing and single-user systems are the anomaly. Part of it is having access to beefier systems for smaller slices of time, but most of it is being able to share data and collaboration between users.

If you're only used to cloud VMs that are setup for a single user or service, I guess your views would be different.

This is overwhelmingly the view for business and personal users. Settings like what you described are very rare nowadays.

No corporate IT department is timesharing users on a mainframe. It's just baremetal laptops or VMs on Windows with networked mountpoints.

Multi-user clusters are still quite common in HPC. And I think you're not going to see a switch away from multi-user systems anytime soon. Single user systems like laptops might be a good use-case, but even the laptop I'm using now has different accounts for me and my wife (and it's a Mac).

When you have one OS that is used on devices from phones, to laptops, to servers, to HPC clusters, you're going to have this friction. Could Linux operate in a single-user mode? Of course. But does that really make sense for the other use-cases?

is it? most HPC (if GPU clusters count) are probably in industry and managed by containers

Containers rely on many privilege separation systems to do what they do, they are in fact a rather extreme case of multi-user systems, but they tend to present as “single” user environs to the container’s processes.

Good software hides complexity. User does not have to understand user group permissions suid etc etc
