This is might be too OT, so my apologies to the moderators if they
agree about that, but I believe this analogy to electronic building
locks is not fairly applied.  When power fails, electronic building
locks do not simply remain locked, but are required to at least unlock
in the direction of egress.  They are also required to have a manual
release device that interrupts power to the lock in the direction of
egress, regardless of whether power has failed or not.  And so just as
the door can be more important than the lock, a system can be more
important than its compromised RAM.
