He's saying that if a program does a push_back when the capacity has been 
reached, this program has a logic error, and throwing an exception will not 
make the error go away.

I'm not so sure of that, because doing a push_back when the capacity has 
been reached is not necessarily a logic error if the code is well aware of 
the possibility and prepared to handle the exception.

try
{
    do some push_backs into a static_vector; we don't know how many
}
catch( out_of_capacity& )
{
    // ignore, what we gathered so far is good enough for gov't use
}
