Yeah. Live patching is someting distros/service providers charge a lot of money for to get right, and requires at least some knowedge about every patch you apply.

And it's something no one operating a PC that regularly reboots needs. Idc if my running kernel is one version older than the one I installed, it doesn't impact games at all. The only exception is loading modules, which is something you rarely do in normal operation. And for the only module I stumbled upon that I regularly loaded after boot, v4l2loopback (or similar), which I needed for streaming my phone's camera to OBS, I added it to /etc/modules-load.d/v4l2loopback.conf.

Even my server's kernel is sometimes out of sync. I only reboot programs I actually want to be up-to-date at that moment. All others can wait for some weekend or another.
