Linux/devtmpfs doesn't give you stable device names, at least some device names depend on the order in which the devices were discovered at boot, which is why most distros today use UUIDs in their fstab.

It's trivial to get stable device names of your choosing. Simply set up a udev rule that matches some unique property of the device, and set NAME=... only nowadays you can't do that: symlinking is all you can do.

The UUID stuff is not magic: it's doing just that, only using RUN= to populate some env vars, then assigning symlinks depending on the value of those vars.
