There's an issue I remembered that almost always forces me to reboot my machines.
On certain Linux based distros after upgrading the kernel you loose the ability to load kernel modules as they'll be installated in /lib/module-<whatever new version> instead of the currently running kernel.

For instance this is noticeable if you've been running a machine for a while without rebooting, during that time you've upgraded the kernel without anything out of the ordinary happening, then one day you plug an external device that needs a module and the module can't be loaded.

Thus, at every kernel update I've built the habit of rebooting.

This, Arch Linux does this and it's quite annoying.

Arch Linux doesn't do this. It's what you get with libe kernel upgrades, so every rolling release has this issue.
It's also an issue with crux for example where you upgrade the kernel yourself whenever you want.
Kernel headers are left in place so you can compile new modules and load them, but it might break afyer reboot

I remember from my Debian days that there were two kernels installed. That way, the modules from the old kernel version would still be around as it was the other kernel that got overwritten after kernel upgrades. This was really convenient.
Debian may not be a rolling release but security updates are very frequent, or else I may have missed your point.
