I already offered a couple of examples that you ignored (just a couple
that came to mind, certainly not an exhaustive list): when you have a
system that doesn't load a kernel from the filesystem, such as a VM
environment where the boot process is external.

Another is if you need to re-install the kernel RPM because files have
been removed, overwritten, etc.; "yum reinstall" is documented (unlike
this magic "feature") to not handle multi-install packages like the
kernel.  The only way is going to be to "yum erase" and "yum install".

Also, even removing every kernel RPM will not render your system
"non-recoverable".  You can always use a boot CD, and in modern Fedora
systems, the "rescue" kernel/initramfs are never removed (not owned by
any RPM), so you should always be able to boot that.
