I'm not sure if this is the "hardware security module" they've been touting for Pixel 2 devices, too.

I assume this project was spun-off from Project Vault, or at least they re-used some of the ideas/code from that, but it's still a shame we won't be getting the microSD "HSM" anymore. I guess that idea died when Google and other manufacturers decided to kill support for microSD in their devices altogether.
