It's special-cased.
recall in FC5 having a an IBM 225 that ran OK with the initial kernels but at some update would not boot the new one and many subsequent versions. I think there were more failing kernels than the number configured to keep but I was always able to recover by selecting the old working version in the grub boot menu so it looked like it was a special case. Eventually I did a bios update on the machine which let the new kernels run but broke the older ones.
You can configure the number to keep to be very large, if you want.
I didn't particularly care about keeping the new ones that didn't boot, so special-casing would be the right thing - just harder to be sure that the default hasn't changed as you update than a config option would be.
