You are assuming limited by your own experience that this is done
accidentally.  On the contrary, because of yum's behavior, its perfectly
fine to quickly do a yum remove kernel to get rid of older kernels and
retain the current one. I do this from time to time if I have to play
around with third party kernel modules and don't want the other kernels
interfering with that process.  The protected packages feature in general
is also useful not because anyone would do yum remove glibc directly but
because other scripts that remove duplicate packages have been known to
have bugs in the past which removed the critical packages instead and the
protected packages feature would prevent such bugs from causing
irrecoverable damage.
