I don't see where the TPME needs to trust the EKP in the specification.

Yep, but why would you allow reseting the EKP? You can reset everything
else because you may need to, but it's no use reseting the EKP.

Not the TPM, only a ***** BIOS and a ***** manufacturer (which can base
their scheme on TPM). We saw this in the past, but we didn't needed a
TPM for that, only human mind. :|

This was the idea, not the argument.

Because sometimes the security isn't only reduced to a passphrase.
Sometime tokens have their uses.

Don't you think it isn't even worth working on?
