Linux is feeling more and more like a bunch of random tools thrown together as opposed to a complete OS designed to work as a whole.
What enshittification?

Linux is a kernel. The user space stuff is a bunch of random software thrown together. That's what Linux distributions are.
This is a ridiculous stretch of the term

ZFS works fine on root on Linux. I use it on multiple machines.

This has quite literally always been the case and seems intentional. Linux is the kernel only, others supply the userland of their choice (aka a Linux distribution).
