Why is 'final switch' required? Another possible way of dealing with the 
same issue would be:

switch(e) {
case E.A: blah; break;
case E.B: blah; break;
...
default: assert(0);
}

Ie, if switch is over an enum type, and the 'default' clause consists 
only of assert(0), the compiler could generate a warning if some of the 
possible enum values never appear in a case statement.

It's not quite the same as 'final switch', but I think it captures most 
of the use cases.
