Using the lock bits, you can make it impossible to overwite the 
bootloader.  That is to say, impossible for the bootloader to overwrite 
itself, even if it misbehaves.  I think that putting a bootloader 
(which is actually a Flash loader, not a bootloader in the proper 
sense) in the microcontroller as the only firmware load facility is 
reasonable.
