Only to activate the new kernel! You can just leave the current one running with minimal issues, even less if you have something like KernelCare live patching security bugs
Assuming any dynamically loaded module will fail, why does KernelCare exist and why is it used so prevalently in web hosting environments? It costs money, so buying it when it doesn’t work seems odd.
On the opposite end here. I know if there’s a kernel update then I’d need to reboot and restart everything.
I still haven’t restarted my system since updating to 6.4

Very valuable high uptime servers exist but they take care, as in professional admins, to maintain it.
None of this applies to Arch or home users. You get full kernel updates and no old modules are kept. You reboot.
Other distros like Fedora keep old versions around but you still have to reboot to get updates.
