Yes, that would be nice.  I don't know much about the Prius battery
technology but I have experienced the sudden, completely unexpected failure
of lead acid batteries.  When a  plate collapses it starts a rapid domino
effect of successive failures yielding a completely shorted cell.  On the
other hand, I've experienced the gradual deterioration of the batteries that
run my cordless drill.  As they age, they hold their charge for ever shorter
periods.  I've got one right now that takes a full charge in the typical 30
minutes, as indicated by the charger's light, but can sustain operation for
only a few seconds.

I'm betting Toyota's engineers will eventually develop a fall-back to the
ICE.  Certainly this isn't going to do anything for my 2005, but perhaps it
will for my 2008 or 2009.

Mostly, it does. This is the first one I've heard of that didn't become
balky and light the warning lights before quitting altogether. OTOH, most of
the on-road failures I've experienced with other cars over the years were
without warning. Clutches and sometimes automatic transmissions give warning
in the way they operate, but pretty much every other failure I've had on the
road was a surprise. Such is life.

The great thing about the Toyota's hybrid transmission is its simplicity.
However, it does mean that the ICE has no low end torque to the wheels, as
it counts on the electric motors to perform that function.  I cannot see any
way that Toyota could provide backup for this kind of failure without
turning their beautiful, simple, reliable transmission into a complete
kludge.  Therefore, I doubt they will ever consider trying to engineer a fix
for this.

Will they bury the victims in a hybrid coffin?
