Might be different depending on the market. For us it was "we can reset, but we have to recover within a few seconds". I never questioned the wisdom of our hardware cert engineers.
(My experience at three different companies spread over 35 years was, if you were a software engineer helping the hardware types with ESD or RFI testing in the lab, you were definitely going to get zapped at some point. That made you part of the team, though ... :-) )
As it was put to me, if a discharge leaks through, there's really good chance that another, or 3rd, or 5th would be fatal: the device is not adequately protected. But probably that's not a big deal in some applications.
