However, I expect that for many newbies, editing a grub config file 
would be an operation accompanied by great trepidation, lest it result 
in an unbootable system.

It's not yum that does this, it's the kernel package post-install 
script. It would not be a good idea to turn off all scripts in yum as 
that would break *lots* of things.

You can prevent removals of old kernels by disabling the installonlyn 
yum plugin.
