You certainly are.  /boot can be read only (and on a "production or critical
system" probably should be), and it gets almost no disk accesses compared
to any other part of the system, so it's pretty pointless to mirror it imo. 

Added to that, if anything _did_ kill /boot, you can boot from a live CD.
