For HD, you'd also need a valid vendor-signed key to do the key exchange (which would get swiftly revoked once public), and/or to crack the trusted execution environment.

This isn't true. Multiple Google devices have had their Widevine keys leaked/recovered and Google has waited around before revoking them since it would break hardware playback on the device or cause other issues. The Nexus 6, for one, has been downgraded from Widevine L1 to L3 as a result.

I guess I'm sort of surprised that a unique key per device isn't common yet...
