Just because the problem is "solved" (i.e. designs have improved to the point where this failure mode is no longer critical), doesn't mean that there aren't better (lower cost/weight and stronger) solutions available if the design constraints are changed by the availability of new technologies.
Now is it as safe or safer than current designs? I don't know, but I don't see a compelling reason why it couldn't be. I'm certain there will be quite a lot of testing and analysis of failure rates, system redundancies and the capabilities of the associated degraded states before regulatory agencies approve the use of this type of system.
