the alternative sucks just as much: there's a severe security hole and
the user thinks he's safe because he enabled the yum cronjob.
(in your "turn on the laptop" scenario you boot often enough that
running the stale kernel isn't an issue, it can be in other
circumstances.

To be honest, the kernel breaking shouldn't happen too much. And as long
as there is a known working kernel also in grub the damage is less than
that of a severe break-in. So I'm arguing for a secure default versus
the "has a small chance of breaking" trade-off you make into the other
direction.

I think chosing for secure is the right approach. It's hard enough to
get people to apply security updates (hey this should be asked in
firstboot: "Enable automatic (security) upadates?"); but if they do then
it'd suck to then give them only a false sense of "I'm secure because
I'm updated".
