The alternative is that sometime in the future, a scheduled or unscheduled reboot leads to trouble and you have no idea what caused it!
I saw somewhere during kernel compilation an option to load a kernel on the fly but I haven't gone further (maybe it was targeted at kernel developers).
So usually, you do reboot after a kernel upgrade if you want to run the new one.
It's the only occasion (I hope systemd hasn't changed that!) when an upgrade needs a reboot (or am I wrong?). Sometimes though you need a simple log out / log in.
