Since a symmetric key have "secret" value more so than "private" value, if we replace "private-key" with "secret-key" above, then yes, I agree.  Stated more plainly, a platform that doesn't have a TPM (or equivalent) protected asymmetric key, could instead protect the operator's symmetric key using NACM (i.e., only the crypto-officer/ restore-session can access it).  Is this what you mean?
