I'm pretty sure the fact that with root permissions you can leak data out of an SGX enclave is news to a few people, like the CCC and anyone who's staked their business to the security promises provided by TEEs. Voltage glitching in person is different from doing it in a repeatable way in software from halfway around the globe. When you've got a Metasploit module for overflowing buffers in trusted enclaves by executing code that drops processor voltage, that's an interesting timeline to live in.
