Yes, but the problem, I feel, is the priority of what gets pushed out to RAM on Linux.

You could split the processes into 2 categories:

1: applications that are doing tasks the user wants.

2: OS processes that the user needs to interact with in order to terminate applications.

There is an argument for applications taking priority: the user wants to do a task, if you move application out of RAM, the task is going to take longer.

But to me OS processes, including the graphical shell (taskbar, windowing system, etc.), should have priority: if an application hangs on I/O, the user NEEDS to be able to use the taskbar in order to terminate the application, otherwise they're going to have to wait who knows how long for the application to finish its task (or just hard reset the computer).

I don't know anything about how Linux handles memory, but the impression I have is that it has its priorities wrong, or it may not even have a way to configure priorities (unlikely), or maybe there is a to prioritize what is kept in memory but it only splits kernel/userspace memory so DE's that sit in userspace don't get priority (i.e. it's inadequate for a graphical operating system).

To be frank, as a desktop Linux user my biggest fear is that the Linux kernel is perfectly capable of prioritizing kernel/userspace memory, but it has no way to prioritize DE's. In other words, that the "graphical OS" use case of Linux is a second-class citizen, a feature bolted on top of GNU/Linux/Systemd. Because that would mean a lot of things are considered only from the perspective of a Linux server. This is only my imagination talking, since I'm not really involved with how Linux works. But to be fair I was never involved with how Windows worked either, and I never doubted it considered desktop a primary use case.
