Like self destructing object that is provable secure after a read x times seems interesting outside DRM. For example a lot newer military hardware uses software to be more effective. So if the gear has to be abandoned for some reason a secure erase sounds useful. How much better than is than current solution of a chip on a glass substrate storing a crypto key with a heating elements or explosive to shatter it dunno. Although glass being brittle makes making sure it does not break accidentally has design challenges. Polymers tend to be more durable.
