My apologies, you mentioned the explosives being 'redirected', when I guess what you meant was that the explosive circuitry would be redirected.
Even so, those checks aren't sufficient to handle counterfeit parts that might only fail under stress, rather than the safe conditions of a ground test.
The best approach is what it has always been: Strict process control of the entire supply chain, rigorous component and subsystem testing under extreme conditions before delivery, deep analysis of failed components coming off the flight line, and regular inspections for anomalies.
