I'm unfamiliar with the current Pd hardware, but I would imagine that secrets
would be generated in a secured compartment they'd be unable to leave (but
for key escrow and LEO backdoors, of course).

Restricting document access is something companies and governments would
love to do. If OO & Co can't ensure interoperability, and the software
is cheap enough/doesn't have strict online activation you'll see it used
at home as well.

It should be possible to implement tamper-proof crypto hardware and
error-less code if it's just a tiny kernel less than a kLoC. (Which doesn't
mean Redmond can do it, just that it can be done in principle).
